When activating an integration, you can receive the following error message under certain circumstances at the top of the Integrations page even though the integration is clearly labeled as Active in the list of integrations.
You are trying to activate integration ”integration_name” which is activated, deleted or locked by another user. This is not allowed.
After receiving the error, click the Search icon on the Integrations page.
Verify that the search confirms that the integration is still listed as Active and the error message is gone.
