Is there a limit to use a particular connection in Glue? I have existing crawlers that work fine with the connector. But when I try to update or create a new one, the error above is what I get. Ideas?

Accepted Answer

Hi,

I see that you are facing the following error when trying to update or create a new crawler with a JDBC connection :

Expected string length >= 1, but found 0 for params.Targets.JdbcTargets[0].customJdbcDriverClassName

This is a known issue on the new crawler UI at the moment. The internal team has already addressed this issue and the fix was currently being deployed. It was live in the eu-north-1 region. I have tested the same on my end and we can now create the crawler using the JDBC connection in eu-north-1 region. This fix is yet to be deployed to all the regions. Meanwhile, as a workaround you can use the legacy console to create/update the crawler with JDBC connection.

Thank you.
