I am working on Solr. I can submit XML files but when i submit JSON, CSV or txt files: "Unsupported ContentType: application/octet-stream Not in: [application/xml, application/csv, application/json, text/json, text/csv, text/xml, application/javabin]"
Error: https://ibb.co/dcyV05
Do you have any suggestion ??
After you create core under documents there is a Request-Handler (qt) which is initially /update. If you change Document Type to File Upload you can't submit your json or csv files.
To solve this problem change Request-Handler (qt) to /update/extract. After that change there will be no error when you submit your files.
