Fixtures DuplicateEntryError

Hello,
I have issue with fixture, I have used it to insert new fields in the Patient doctype After installing the app by calling it in the hook using fixtures = ["Custom Field"]
After this, every migrates to bench cause DuplicateEntryError

How can I make this run just once, when installing the app? and ignore it then when I migrate the bench?

Thanks

Solved By following the commands and be patient :smiley:
