    Invalid map key when replacing data source

    Tobias Marty

      We're changing our database system from Microsoft SQL Server (extracts) to MySQL and we're trying to replace the data sources of our workbooks.

      Unfortunately I get a rather cryptic error message "invalid map <K, T> key" with every single data source.

       

      What does this mean and how can I work around it?
