ERROR An error occurred (ValidationException) when calling the GetTables operation: 1 validation error detected: Value 'big_value' at 'expression' failed to satisfy constraint: Member must have length less than or equal to 255

Hi @parshnt,

This looks like a server-side validation error. Can you please provide the output with debugging turned on? You can add boto3.set_stream_logger('') to your code to do this. Please be sure to redact any sensitive information.

Thanks!

@kdaily attaching the debug logs

on that note some things I've observed:

• This happens only when the job runs on our EKS cluster, the local system seems to be working fine
• I've updated the boto3, botocore to the latest available versions (at this time) and the issue still persists.

glue-get-tables-debug.log

I've attached a subset of logs (relevant to the issue, w redacted info). let me know if anything else is needed (can share over a secure channel w you).

@kdaily have you been able to validate or replicate the issue?

Hi @parshnt I tried to reproduce this but wasn't able to. Instead I got the following error once exceeding 2048 characters: '...' at 'expression' failed to satisfy constraint: Member must have length less than or equal to 2048

If you update to the latest version of boto3 do you still see this issue?

Since we haven't heard back in a few weeks I'm going to close this issue. Please let us know if you're still running into this issue and we can revisit it. Thanks!
