Same error. Hope someone helps.

Which version are you using ?? it seems fine 0n 8.x.x can you provide details.

ERPNext: v8.x.x-beta (b9939a6) (develop)
Frappe Framework: v8.x.x-beta (124444b) (develop)

I,m using it on my own server and it seems to work fine all the system but every day i get some instant errors saying TypeError(“‘int’ object is not iterable”,)
