Liveview upload failure of a hundred 2KB files
I am learning elixir/phoenix/liveview so please bear with me.
I tried uploading one hundred 2KB files to stress test the LiveView upload module and it failed. By fail I mean the @uploads socket is populated, tokens are generated for each file, long pause and then the page just reloads,
How do I find out what actually caused the failure? I know the failure happened before submit but there are no indication as to what actually crashed(?) the app. Is there a log I can enable or something I can do to learn more about situation?
Many thanks in advance.

It seems to be similar (at least to me) to the issue below.
My sequence of events is like:-
- I press Submit to upload one hundred tiny files.
- phx-submit event is triggered
- Liveview upload starts working on preparing all the files for submission
- handle_event() that is suppose to handle the submit event timed-out since Liveview upload is taking longer than usual to prepare the 100 tiny files I selected
- Page refreshes since the event timed out
plausible?

It seems this issue happened to other users as well. It wasn’t resolved in Liveview, user resorted to a workaround by using an external uploader…
