AttributeError: ‘PurchaseInvoice’ object has no attribute ‘project’

May we know what command produced the message? Also the version of ERPNext and how and when installed?

I am seeing the exact same error when I attempt to submit a Purchase Invoice. (As far as I can tell, any Purchase Invoice. It saves as draft fine, but I can’t Submit it.) I am running the latest develop version of frappe and erpnext, just updated today. (specifically, commit ac23ac6 of ERPNext). Thanks for any help/thoughts/pointers. – Glen Whitney

The two-line patch at the end of this posting alleviates the error for me and seems to result in perfectly good general ledger entries. However, I am not familiar enough with the code for PurchaseInvoice to know if this is a reasonable long-term solution or if this problem is a symptom of something else that should be fixed independently, or even some misconfiguration of ERPNext by both me and the OP. That said, if you would like me to file a pull request for this small change, referencing this thread, I am happy to. Just let me know.

Yes same here

Does this resolves the issue?

It does for me (note the extra + that snuck in to your posting from the “diff” format, that should not be in the code). But it remains to be seen if the ERPNext developers feel this is the proper way to modify the code, hopefully someone will weigh in on that. If not, I recommend filing an issue on github frappe/erpnext if there is not one already, or I can if you like. Best, Glen

I also got this issue when i upgraded to the latest v12. The solution is to run the following command :
bench --site your_site_name migrate

replace your_site_name with your own site.
