I've got a Nintex workflow which saves a document on the document library. It uses a Template URL (.docx). I had to change a column name on the list library. So I deleted the column and created a new one so it matched the internal column name. The workflow completes its steps but during document creation (I think), there is a hiccup. Error message say "Filter rule error, column '120' does not exist. It may have been deleted by another user." The document generated in the document library shows unfilled columns in word. Internal status of the workflow becomes "Suspended". I've not been able to debug this. If anyone has come across this issue on SharePoint online, please help me out.
PS. I checked the permissions per link below and made sure all permissions are there.
