Could you please check if the server is problematic using a local server that serves the file?

This strikes me as an issue of having too many processes resulting in some kind of resource problem. Do you know if this occurs always with, say, 100 processes?

Yes.

Could you paste the log output for both runs?

Is it possible that interruption are leading to scripts loading in a bad order?

One way is to ensure code that rely on each other are sent in one request (not chunked). If sending a single file works, then this is definitely a chunking...

@robbimount Could you rollback versions to identify when it last worked?

Please provide an example script.

Please open a bug with `puppeteer-extra`. In general, we recommend posting this on stack overflow and discussing it there until the scope of the issue can be found.

Could you verify if this occurs with different time zones? If it only occurs due to a duplicate call, I wouldn't necessarily call this a bug.
