We recently added some validation on that endpoint. The

Invalid property: params => Expected array, received null (7400)

Invalid property: params => Expected array, received null (7400)

Invalid property: params => Expected array, received null (7400)

Invalid property: params => Expected array, received null (7400) seems to be coming from that validation. The

params

params

is an optional list argument that should only be provided if you have bind parameters in the SQL query.

I will see if we can make the

params === null

params === null

params === null

params === null be treated the same is not provided at all, since

null

null

is not a valid value per se for that list argument.

When i changed the code to include a string array with params i started getting:

Not sure what you mean here. Did you provide an empty slice?

The SDK docs explicitly mention that non-provided fields are not sent: https://github.com/cloudflare/cloudflare-go/tree/main?tab=readme-ov-file#request-fields

All request parameters are wrapped in a generic Field type, which we use to distinguish zero values from null or omitted fields.
This prevents accidentally sending a zero value if you forget a required parameter, and enables explicitly sending null, false, '', or 0 on optional parameters. Any field not specified is not sent.

Weird that in your case @dimsid

null

null

is being sent for

params

params

. Did you not provide it at all (as your snippet above implies), or did you provide it explicitly as null?

Can you upgrade your SDK version used to https://pkg.go.dev/github.com/cloudflare/cloudflare-go/v4#section-readme and try that?

Let me rephrase my problem so that i can be clear!

I have a golang script using cloudflare-go sdk version 0.89.0.

In my scipt there was this code:

res, err := c.api.QueryD1Database(c.ctx, cloudflare.AccountIdentifier(c.cfg.Cloudflare.AccountID), cloudflare.QueryD1DatabaseParams{
DatabaseID: c.cfg.Cloudflare.DBID,
SQL: sqlQuery,
})

and it was working.

Last Monday 3 March 2025, this script stopped working, with this error:

Invalid property: params => Expected array, received null (7400).

Following the error message, I updated my code to this:

res, err := c.api.QueryD1Database(c.ctx, cloudflare.AccountIdentifier(c.cfg.Cloudflare.AccountID), cloudflare.QueryD1DatabaseParams{
DatabaseID: c.cfg.Cloudflare.DBID,
SQL: sqlQuery,
Parameters: []string{},
})

and the 7400 above was gone but a new error ocuured which is this:

error from makeRequest: received internal server error response (HTTP 500), please try again later

And I am wondering if except from the validation check you mentioned, something else also changed and my query does not work.

As mentioned i am using sdk version 0.89.0 and I would not like to make a version upgrade to v4 if possible

As I said, there is a new validation now on our API for that endpoint. The error you get

Invalid property: params => Expected array, received null (7400)

Invalid property: params => Expected array, received null (7400)

is from that validation. That old version of the Go SDK I believe sends

null

null

when it should not send anything.

I already made an improvement to allow

null

null

s for now for these cases, but it needs some time to be rolled out.

I do suggest upgrading at some point though to make sure you get the improvements of the SDK.

lambrospetrouOP•3/10/25, 1:44 PM

It's not fixed really. By passing empty array you trigger some other flow to fail since the params should not be empty. That's another thing to be fixed somewhere across the path, either in the SDK or the API itself to return a proper error instead of 500.

I am rolling out the validation fix to not fail with

null

for now so your original code should continue working once that's out everywhere.

Make sure you don't have any typos when querying the table. In the UI console run select * from sqlite_master;select * from sqlite_master; and see if the output contains the table you expect to be there.

lambrospetrouOP•3/11/25, 11:31 AM

This is not a bug that can happen randomly. The query must be wrong in the worker that fails. Either the table always fails to be found, or never.

Sveinn•3/11/25, 3:54 PM

Hey,

A few weeks ago, my Cloudflare account started racking up a massive bill. I reached out to support to figure out what was going on, but it took around 20 days to get a response. The reply just said the billing was correct but didn’t explain what was actually causing the charges. I asked for clarification about a week ago but still haven’t gotten an answer.

After digging into it myself, I found that a simple uptime check my load balancer does every minute was somehow pulling tens of thousands of rows each time, leading to crazy charges. I’ve stopped the uptime check, but now I’m stuck with a credit card bill of thousands of dollars for my small hobby project.

Is there any way to get in touch with support to discuss these charges? @lambrospetrou

I have two workers that bind into the same D1 database:

...
[[d1_databases]]
binding = "FIRESTORM_DB"
database_name = "firestorm-db"
database_id = "c020574a-5623-407b-be0c-cd192bab9545"

migrations_dir = "../d1/migrations"

I have set the database id to be the same for both. However, when I run this locally for testing and start up one worker and have it add data to the db the other worker has no recollection of it. Is there a fix anyone knows about?

Kenny•3/13/25, 3:36 PM

I should also mention that I went into each .wrangler/state/d1 to check the sqlite data directly and it seems that each one spins up it's own sqlite db for local testing. I looked through the docs and haven't found anything that could solve it yet.

const id = this.env.MY_DURABLE_OBJECT.idFromName(teamId);
const stub = this.env.MY_DURABLE_OBJECT.get(id);

const id = this.env.MY_DURABLE_OBJECT.idFromName(teamId);
const stub = this.env.MY_DURABLE_OBJECT.get(id);

But how should I manage auth? Shouldn't auth hit a single DB?

Should I be using D1 for tables like - users, teams, etc (other global tables) and DO for tables specific to the team?

I would personally stick to and recommend something more traditional and external for auth and global info. Postgres + Hyperdive for example works great.

Cloudflare’s recommendation to build horizontally with D1 and DO SQL just doesn’t really work in my experience in the real world, coupled with the reliability issues and support concerns with D1: https://www.reddit.com/r/CloudFlare/s/4D9AeoAHm0

Thank you. I didn't see anyone building auth on top of D1. And so the question.

James•3/15/25, 3:52 PM

I use a central db for auth, but they only need to hit that when the session expires, as well I only store data there for central lookups. Sessions are kept in DO per user, bypassing central db for a faster request avg.

Why would Prisma need access to the filesystem if it is configured to connect to D1? Its a real showstopper for me. I guess i will have to self-host the app if there is no solution.

Hi! I'm looking for some docs on how d1 handles a colo going doing? If the location housing my d1 database goes down am I just hosed until it comes back up or is their some kind of built in failover?

Zack•3/17/25, 4:53 PM

Hey, I recently moved some of our infra from KV to D1, with a database situated in every location to be nearer to the user while awaiting global replication. This was working great, however after updating that data through our warming process (import all new data into a tmp database, rename old database, rename new database to old database name, drop old database), the databases all appear to be experiencing significant random latency issues. In our monitoring I can see average duration to call D1 jumping from ~20-50ms depending on worker location to some queries hanging for multiple seconds up to a minute. I'm wondering if someone can help me investigate what is going on here. Beyond completely recreating all these databases as part of our warming process I am not sure what the option is here. Our database is ~2GB in size and has 3.24 million rows. I am wondering if there's something going on internally like DO resets that is causing this behaviour. I've attached an example graph where you can see the moment the warming happened and the duration metrics afterwards. This is from the HKG PoP and with a D1 instance in APAC

lambrospetrouOP•3/17/25, 6:59 PM

D1 is built ontop of Durable Objects (DO). It's true that once the colo hosting the Durable Object for your database there will be some downtime. But, the Durable Objects platform will move your database DO on a healthy colo/server as soon as the faulty colo is detected by the automation and taken out of the network. Depending on how severe the issue is this move could take seconds or a few minutes. Usually there shouldn't be much of a downtime for this reason.

Unfortunately, most of the errors you will encounter are transient and sporadic, not a whole colo going down. In those cases, making your queries idempotent and having some retries will greatly help.

lambrospetrouOP•3/17/25, 7:02 PM

You need to provide us database IDs to be able to look anything for you.
Also, some details on volume, queries, how much data are you returning each time, etc are helpful.

This is from the HKG PoP and with a D1 instance in APAC

APAC is a huge region and you could be 100-200ms away from your database unfortunately. Having said that anything more than a few hundreds of ms even in those cases is a bigger unexpected issue, either with the responses getting back to your worker or something else.

Also, I assume you are using the Workers binding right? Not the REST API.
