Trying to upload a csv file as a Data Set, fails with:

knowage-server-docker-knowage-1        | [Fatal Error] :2:1: Content is not allowed in prolog.

To Reproduce
Steps to reproduce the behavior:

  1. Start knowledge-server using the docker-compose, based on knowagelabs/knowage-server-docker:8.1.0-SNAPSHOT image.
  2. Login as biadmin or biuser
  3. Go to Data set
  4. Introduce the details on the Details tab, go to Type, select File, upload for example: https://landscape.cncf.io/data/items-export.json (was looking for a public .csv to be used for this bug, with which one can reproduce the issue)
  5. Got the pop-up error:
Error
Impossible to parse file. Please, check its content and upload it again

Going to the logs:

knowage-server-docker-knowage-1        | [Fatal Error] :2:1: Content is not allowed in prolog.
knowage-server-docker-knowage-1        | [Fatal Error] :2:1: Content is not allowed in prolog.

Expected behavior
Expecting to proceed analyzing the data set using the BI tool.

Hello,
the link that you have attached points to a JSON file.
At the moment you can only upload CSV o XLS files.

Can you try again with a CSV file please? You can generate a random one at https://www.mockaroo.com/

Thanks,
Marco
