I created a service account, and created a credential for that service account, but I am still getting the error in ISC when I test connection:
[ InvalidConfigurationException ] [ Possible suggestions ] Ensure that the configured Email Address is valid and has Atlassian administrator permissions. [ Error details ] Configured Email Address is either invalid or has insufficient permissions.}
I granted all the permissions possible, and still got the error.
I see a similar question has been asked before - but the solution did not provide details.
Click “Create API token” (i.e. created a token without scopes)
Used this token along with my email address in the Connector connection settings
The above token worked.
What didnt work:
Creating a token with Scopes didnt work
Creating a token for a service account didnt work
Creating a token under https://admin.atlassian.com/..…/api-keys didnt work for Site Admin API token (Edit: but this was the token I needed for Org Admin API token in order to enable/disable accounts)
