    Error when running output: failure evaluating to database

    Robin Weil

      Hi, everybody


      I'm facing an error with Tableau prep as I am running a flow including 4 joints to combine Excel sheets.

      The error message says (see also attached image):

      "Unable to run input node: Async operation failed for request 142 with error code 4 and message: failure evaluating to database: could not send data to server. No process is on the other end of the pipe"


      Actually, I'm not even using a database as input or output for this flow. The input data is saved on Onedrive but the same error occurs when using local copies of the files. The data itself is not very large (biggest sheet has 200000 rows and 25 columns)


      Has anybody faced similar problems?

      Thanks for your help!
