On ERPNext v13.0.0-beta.11, I went to: Customization → Customize Form, then searched for “Sales Invoice Items”.
Then clicked “Add Row” in the bottom of the table and filled it with:
Label: Service Date
Name: (will be auto-generated after saving to service_date).
Then clicked on its pencil icon to edit it and set enabled “In List View” as well as “In Preview”.
Then clicked on “Update”.
Doing this seems to have broken the UI:
I can’t go anymore to any of the other Form Types in “Customize Form”.
It always says “Not Saved”.
After rebooting the docker image and trying to save the Sales Invoice, I get this error message:
