The configuration file for roles isn’t being created likely due to incorrect file paths, permission issues, or a faulty save process. Ensure proper directory write permissions, verify the file path, and check the code or process handling the save functionality for errors.
I want to save some configuration of roles how can i do that i found that no file is getting created
You can use Fixtures:
fixtures = [
{“dt”: “Custom DocPerm”, “filters”: [[“role”, “=”, “Guest”]]},
]
And then run bench --site [sitename] export-fixtures
If you face any problem then ask me 
Thank You So Much Dear
