Because of an issue that’s preventing Tableau Bridge 2018.2-2018.3 from performing extract refreshes, Tableau strongly recommends that you upgrade to Tableau Bridge 2019.1 or later. For more information, see the Error "There was problem and the data engine could not start properly" when Refreshing Data in Tableau Bridge article in the Tableau Knowledge Base.
When an extract refresh failed, there was no visual indicator to show which connection within a data source had the issue.
Sometimes, the text was cut off in error description tooltips.
Sometimes, the words "data source title" appeared in the Bridge Client instead of the actual title of your data source.
Sometimes error messages were cut off when a scroll bar was present.
