[Bug]: error with --no-viewer argument in rc3.0.0.rc3

[chengzhuzhang]

What happened?

When running e3sm_diags command line, I got nboundLocalError: cannot access local variable 'prov_paths' where it is not associated with a value, which i think is introduced new in rc3.0.0.rc3. It was tested okay in rc2.

What did you expect to happen? Are there are possible answers you came across?
