Wappler crashes after editing custom query server-action

Wappler General Bugs
1

Wappler Version : 7.1.2
Operating System : Windows
Server Model: NodeJS
Database Type: Supabase
Hosting Type: Docker

After building and saving a "Database Custom Query" step Wappler crashes and all unsaved progress is lost.

2

What is the custom query you’re using?
Does it happen with a specific sql code or with any custom query you make?

3

It doesn't happen every time, nor does it happen with specific queries. If I reopen Wappler and re-create the same query, the query is saved normally.

4

Please restart Wappler in debug mode and try to recreate the issue. When it happens again, locate and send us the debug log as explained here:

I have the logs here after Wappler crashes:
