The Datasource ID is stored in the browser cache. When logging into CloudSOC and going to the Audit page, the datasource ID from the browser cache may be used to access the datasource, but that ID may no longer be valid. When this happens, the datasource ID is requested again. So no functionality is lost. This is just a cosmetic error.
Log out of CloudSOC properly, then manually enter the URL https://app.elastica.net into the browser and log in again and the error should not reappear.
