Good morning,
I upgraded to V8.1.11 from 8.1.9 and the templates I had connected and working with the tags by removing the tagprovider in the tagpath in order to point to the Default tag provider, it no longer works. I get this error:
In V8.1.9 I assigned the tag like this without any errors: (i have tested also with [ ] before tag path)
Thank you for reporting this issue. I have confirmed that this change in behavior started in version 8.1.10 and above and have submitted an issue to the dev team.
The fix for this issue was merged today into our codebase and the fix will be present in 8.1.13 (it was reported too late to be in 8.1.12 that is going through final verification). It should be in the 8.1.13 nightly download start tomorrow morning (11/13/2021).
