I'm unable to upload users_0.json file from step 13 of Kibana Fundamentals. See error below.
Hi - I cannot reproduce your issue. The file uploads fine for me. I wonder if the file could be corrupt. Can you try downloading it again, and importing the newly downloaded file?
If that does not work, can you please share the version of Kibana you're using? That will help us investigate the issue.
