Problem statement

When attempting to login with any of our applications we are seeing the following error message:

{
"error": "access_denied",
"error_description": "Must provide a domain"
}

Cause

This error was being thrown by an Action, when attempting to use the value event.secrets.auth0Domain when creating the ManagementClient but not configuring any secrets for this Action. Therefore, it’s inputting a null value in the domain attribute, and the error message “Must provide a domain” is saying that the domain needs a valid value.

Solution

This issue can be resolved by adding all the required secrets for that Action, which for the ManagementClient includes auth0Domain, clientId, clientSecret.
