AI mange to find DB location from command
wrangler d1 info <db_name> , which tells me my db is in Wesern north america, while the only time i ussed it ws from AU. Now I am moving my DB Back to AU by creating new db/exporting data to it.Acommand
wrangler d1 export --remote <db_name> --output=x_backup.sql does not create DDL & DML in correct order. (Table being referred get created later.).
TPretty sure the answer to this is no. Cloudflare announced some D1 changes last April. Maybe they'll have more updates around the same time this year.

DHello! 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

LIf you query your database directly or through the dashboard UI console does it work? That error message is not a D1 error so not sure which layers fails for you there.
Dyes 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.

Invalid property: params => Expected array, received null (7400) seems to be coming from that validation. The 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 be treated the same is not provided at all, since 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?
DI mean i fixed the 7400 null error by passing an empty string array. But after fixing this error i started having the ""error": "error from makeRequest: received internal server error response (HTTP 500), please try again later"}"
Ahi! can someone confirm that "bound parameters" refers to the total number of args passed into the query?
A*number of placeholders
LThe 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
Weird that in your case @dimsid
Can you upgrade your SDK version used to https://pkg.go.dev/github.com/cloudflare/cloudflare-go/v4#section-readme and try that?
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 is being sent for 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?
DLet 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

I do suggest upgrading at some point though to make sure you get the improvements of the SDK.
Invalid property: params => Expected array, received null (7400) is from that validation. That old version of the Go SDK I believe sends null when it should not send anything.I already made an improvement to allow
nulls 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.
DHello thanks for all the replies! As i described above the 7400 error was fixed. What about the "error from makeRequest: received internal server error response (HTTP 500), please try again later"
LIt'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
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.DThank you! I would appreciate if you could let me know with a reply here, when this is rolled out
LShould be complete now. Please let me know if you still get that validation error.
DThanks a lot for all your support! it is working now
LMake sure you don't have any typos when querying the table. In the UI console run
select * from sqlite_master; and see if the output contains the table you expect to be there.LThis 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.
SHey,
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
