What does "build an SQLite database separately" mean? You mean uploading an existing SQLite database file?
If yes, you can use the import API: https://developers.cloudflare.com/d1/best-practices/import-export-data/

Hello! I am using a D1 database and have golang script for upserting some rows in D1.

The cloudflare-go sdk that i am using is v0.89.0.

Everything worked good until last Monday that i started getting this error:

failed to upsert customers to D1 {"error": "error from makeRequest: received internal server error response (HTTP 500), please try again later"}

Any known issue or api change?
Wasn't able to find a relevant changelog

dimsid•3/10/25, 10:37 AM

yes quering the d1 directly from the Ui console works.

I have noticed some other api compatibility issues that i have fixed.

My code was originally like this:

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

The first error that i started getting was this:

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

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

failed to upsert customers to D1 {"error": "error from makeRequest: received internal server error response (HTTP 500), please try again later"}

This started happening one week ago.

We recently added some validation on that endpoint. The

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

seems to be coming from that validation. The

I will see if we can make the

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

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?

dimsid•3/10/25, 1:19 PM

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

lambrospetrouOP•3/10/25, 1:26 PM

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

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.

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"

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?

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.
