Issue: Failing access to edit/execute AML notebooks
Solution: It seems that after starting to use Key-Vault, the user needed to switch to Azure RBAC to add the "Key Vault Data Access Administrator
" role. However, after doing so, they started seeing errors. It appears that the errors may be due to missing some basic roles.
After adding these roles, it worked again.
Thank you again for your time and patience throughout this issue.
Regards,
Vasavi
