[bug] Error 500 when uploading artifacts

Hello,

I've been trying to upload some huge artifacts (Android NDK, > 1GB) and I've got this output:

WARNING: Uploading artifacts as "archive" to coordinator... failed  id=787538887 responseStatus=500 Internal Server Error status=500 token=PMbGZV1d
WARNING: Retrying...                                context=artifacts-uploader error=invalid argument

Is it a size limit issue? It seems a bit surprising to get a 500 here.

Current Results

Returns a 500 Internal Server Error when artifact uploads > 1GB are being attempted. It's exceeding the 1GB upload limit.

Expected Results

Return a more user-friendly error instead of a 500 Internal Server Error when artifact uploads > 1GB are being attempted. It's exceeding the 1GB upload limit.
