HTTP/1.1 500 Server Error caused by NullPointerException

W3001 : Error while executing plugin: HTTP/1.1 500 Server Error There was an error running the data mapping process caused by NullPointerException: (SRV000012)

What ever I try, I have this message when I run the workflow at data mapping step.
I set the server configuration with and without security. Restart the windows services at each changes so to be sure.
The Workflow Services run with my windows account that is full domain admin on every thing.

Also in the log:

  • Starting plugin Execute Data Mapping - 09:19:23
  • Sending file data source…
  • File Data Source ID: 13969
  • Sending data mapping command…
  • Failed with cached configuration, trying with upload.

Where the help so to configure the cache?

The cache is not the issue here: the message you see simply means Workflow did not find the configuration in its list of cached files, therefore it uploads it to the server prior to launching the data mapping operation.

Your error seems to be with the Data Mapping configuration itself. Are you certain that if you open the configuration with the Data Mapper and this specific data file, everything works correctly? In the Data Mapper, you can easily double check this with the Validation tool (Alt-V or click on the button with a check mark in the toolbar). Note that the validation is only performed on the number of records specified in the Boundaries’ Record Limit field, so you may want to increase this value in order to validate more records.
