Issue Modifying Custom Doctype in Frappe

I’m encountering an issue with my custom doctype in Frappe. When I attempt to modify the doctype, I receive the error: “Value cannot be changed for Created By.” Additionally, I’m unable to add new fields.

Has anyone experienced this issue? Any guidance on how to resolve this would be greatly appreciated.

Migrate the site and check it.

I am facing same issue. I have create one custom doctype and take a dump in another site . while changing its module i got this error.

i have tried by running migration command and clear cache and website cache command but still issue is not solved.
