Is there a filename limit or special characters that break diagnostics uploads? I was getting some errors with a rather large filename (all the targets were included):
2023-04-27 19:55:11,681 ERROR numerapi.utils: Http Error: 500 Server Error: Internal Server Error for url: https://api-tournament.numer.ai/
2023-04-27 19:55:11,684 ERROR numerapi.utils: Did not receive a valid JSON: Expecting value: line 1 column 1 (char 0)
```,
but it went away if i renamed the file to `smallfilename.csv`
