Issue Summary

I set up a AWS Athena data source in a AWS-hosted redash instance. Whenever I try to refresh the schema, it fails. The error is. “Schema refresh failed. Please try again later”. If I look into the network traffic, the “schema” endpoint returns

{“error”: {“message”: “Error retrieving schema.”, “code”: 2}}, but also a 200 status code

I tried looking into the server logs at /var/log/supervisor, but didn’t find anything. I wasn’t sure what exactly to look out for though.

Technical details:

  • Redash Version: Redash 4.0.1+b4038
  • Browser/OS: Chrome, OSX
  • How did you install Redash: ami image + update to 4.0.1

Turns out there was something wrong with the metadata of one the tables in the Athena schema. Deleting the offending table fixed the issue.

Please how did you identify that the problem was with Athena schema?

Thank you!

HI @ericsousa,

I found the issue by trying to query the Athena schema from the AWS web console. There, I got an error message to that effect.

Best,

Ellen
