Example of the error message

Resolution

Salesforce Admins can resolve this error in Salesforce by checking the following:

‍1. Confirm UserGems is installed as a connected app

In Salesforce, navigate to Setup → Apps → Connected Apps → Connected Apps OAuth Usage → UserGems → Install

In the Connected Apps list, UserGems might be listed alphabetically OR at the VERY BOTTOM of the list

2. Configure user access

Once UserGems is installed, click Manage App Policies and ensure Permitted Users is set to All users may self-authorize (default)

If set to Admin approved users are pre-authorized, you must assign a profile or permission set to the intended users with “UserGems” added in the “Assigned Connected Apps” section before they sign up.

3. Re-Connect in UserGems using the signup page
