I found the 500 error problem.  
It was because of lookup field in baserow. Hmmm…

When I have lookup fields and try to create a new row using api, it keeps returning 500 internal error.  
Once I removed lookup fields and a new row was created successfully via api.

> Hello All, Facing a problem trying to duplicate a database. I have this message: “Something went wrong during the duplicate\_application job execution” Any idea? Thanks, Toni

1. Can I know why this happened?
2. This sounds like I can’t use lookup fields??
3. Have your team fixed this problem in a new version or not?

Please let me know.  
Thanks.
