I also didn't have any issues loading the file. It looks like the error you're getting is an Elasticsearch-specific error. A few thoughts:
- You could check in the Elasticsearch forum since it is an Elasticsearch error. I suspect they'll first give you the general advice for this error which is to set an increased value on
http.max_content_length. The default is100MBso that doesn't seem like it would be the issue. With that said, you should certainly give it a shot first so you can say you've tried it. You can find more info here - If it isn't too much trouble, you might try upgrading your Elasticsearch instance to 7.7.1 on the off chance it's a bug that was fixed.
- You can always fall back to a more standard approach to file upload
If neither of the first two options work out, you should consider submitting a bug. There's always the possibility someone else is seeing the same thing whether we can reproduce it or not.
