Is it still giving issue when you save the dashboard and reload it? Usually, this error is thrown when we try to drilldown from the dashboard in the Edit Mode.
If this a persistent issue, there may be an issue in the URL that is created from the search query, does the query contain any special characters such as +, &,< etc.? These characters need to be encoded. If possible, can you send the query that you want to show in the new tab to debug further?
