Not able to update a jsonb field to null

Help me!
1

Expected behavior

When I empty the input of a jsonb field, I want it to set to null.
The field is nullable in both forest conf and in DB.

Actual behavior

The field reverts to the previous value once I hit save. I get the success message telling that the entry has been saved.

The CREATE works well when I leave the input blank : the field will be set to null.
Error is only occuring on an UPDATE for me when the field has been set to some value and then I want to set it back to null.

Also I can update the field to any other value and it will work, I just cannot set it to null.

Failure Logs

When looking at the logs, I would be expecting and UPDATE statement, but I only get SELECT.
But no error.

Hello @lucas-greenly,

Thanks for your message and welcome to our community! :raised_hands:

I just tried out your use case myself and indeed, it is just impossible to set null to the JSON value.
I am creating a bug report as of now and I’ll let you know when it is fixed.

Thanks for your report!
We’ll do our best to solve this asap.

Cheers.
