A field with the name 'auto_repeat' already exists

ERPNext: v13.0.0-beta.5 (version-13-beta)
Frappe Framework: v13.0.0-beta.6 (version-13-beta)

I tried below command but no luck.

bench update && bench migrate 

can anyone help? I will be grateful for your valuable effort.

When did you get this error? Could you elaborate on the steps followed? Are you trying to add a field called auto_repeat via customize the form in the Sales Invoice? There is already a field called auto_repeat in the Sales Invoice doctype.
