Troubleshooting
Failed to Add/Update a Custom Audience - Error "2650"
Issues: While adding users using the Add Emails/Users to a Custom Audience module, it returns the following error:
- Error "2650"
- Failed to Update Custom Audience
- (#2650) Failed to update the custom audience: This audience was created from data source FILE_IMPORTED.MULTI_HASHES, which does not support data source FILE_IMPORTED.HASHES_OR_USER_IDS. (2650, OAuthException )
Reason: Facebook Custom Audiences won't let Integromat add emails or users unless the Custom Audience were created by Integromat. This error indicates that the selected Custom Audience wasn't created by Integromat, but by another platform or via manual upload.
Solution:
- Create a custom audience from Integromat using Create Custom Audience or other modules using a scenario.
- Now go back to your previous scenario, and add your member to that newly created custom audience.
