Bug reports
1

I have implemented a driver for MonetDB by extending Postgresql driver
It was working fine with Metabase v0.48.3 OSS
But after updating to Metabase v0.50.28,
i cannot view data of any tables, with Error:
"Error preprocessing query in metabase.query_processor.preprocess$ensure_legacy$fn__67773@e08cc27: No fields found for table

we changed a lot how the drivers work between 48 and 50

Do you have any documentation to follow or any related content.
We are at the verge of release, and it blocked the release.
Your help would be greatly appreciated

4

Is the documentation updated with the changes:

any other material that can help?

Just to update we are using Metabase Enterprise license
