Got an error PGRST102: Error in $: not enough input when inserting the data using supabase js

Bug report

We got a 400 error with Postgres error code PGRST102 and message: "Error in $: not enough input" for a simple inserting call by using supabase-js. But after that, we check the supabase, we can see the new record.

To Reproduce

I have a simple_test table which uses to reproduce the bug with the structure below

create table simple_test (
  id uuid DEFAULT uuid_generate_v4(),
  name varchar(512) not null,

  primary key (id)
);

In the next.js site, it uses supabase to insert data

supabase.from('simple_test').insert({ name: 'sample' })

After that, I use the Network tab in Chrome to see the request, it returns an error:

message: "Error in $: not enough input"

I tried to set up another supabase project, and the response is the same but including the code PGRST102.

Not sure how to fix this bug because seem it’s a simple call. Please help to point to me what I should do, thank you

Expected behavior

The data was inserted successfully so the response should have an HTTP code should be 200 and include the inserted data.

Hey everyone. Just to let you know that we’ve isolated the error to a bad processing of the JWT in our Cloudflare workers. We’re working on a fix.

This has fixed it for me too, any chance this can happen again? caused lot of a pain for me in production

@farzd Sorry for any trouble caused. The infra team is now adding regression tests to ensure this doesn’t happen again for the Cloudflare workers.

To clarify, this happened because an exception during the JWT decoding caused cloudflare workers to resend the request without a body(hence the error message mentioned above). More details here.

The REST service is thoroughly tested and these kind of errors wouldn’t make a stable release or even a pre-release.
