I followed this guide exactly but when trying to get project_name into my sales invoice with {{ doc.project_name }} it just says “None” on the invoice.

Is the fetch pulling the project_name through? Would be helpful to know if the issue is with the fetch or the jinja code. Everything looks ok from your post though 
Hi @Rick-Hard89,
If the version is not updated then please update it and migrate it.
It’s worked on the below version.
# Vesion
ERPNext: v14.31.3 (version-14)
Frappe Framework: v14.41.0 (version-14)
Thank You!
I’m on a fresh install of frappe(14.42.0) and erpnext (14.32.1), also have some other modules installed. Yesterday i tried to do a bench migrate but it was still the same.
Today when i tried making a new timesheet and chose the project the project name showed up for some reason even though i also did the same yesterday without it showing up. Now it’s working correctly and it’s also showing on the invoice.
But i also have another strange problem with my ERPNext, the sales tax on items disappears when i save the invoice. Another person also have the same problem on this forum. Could it be something with the newer version I’m using?
Thank you very much for the help!

I suspect it was the module POSAwesome that had something to do with the problems we had. All works well now that i reinstalled it without that module
