Description

When sending a file, during the upload operation about at the 95% completion, I got an exception with message text related to 'RPCError 400: INPUT_GZIP_INVALID' which abruptly aborted the upload operation and telegram-upload.exe process terminated with exit code "1".

Here is the Traceback's stack trace:

telethon.errors.rpcbaseerrors.BadRequestError: RPCError 400: INPUT_GZIP_INVALID (caused by SaveBigFilePartRequest)

After I got that error, and as shown in the image above, I was able to try again to upload the same file (this means run again telegram-upload.exe using the same parameters as before), and this time the file was uploaded successfully without errors during the upload operation.

I don't know anything about Python more than the very basics, so I will not enter to discuss on that, but I can discard that it could had been a random network disconnection problem since on the background (me doing other things unrelated to telegram-upload) I was using other program that depends on staying connected.

What I Did

I did nothing strange, just a programmatic, automated call to run telegram-upload.exe passing to it the next command-line parameters to upload a file:

telegram-upload.exe --force-file --caption "" --to "{telegramInviteLink}" "{filepath}"

The program that can be seen in the image that I shared which is automating the telegram-upload.exe execution, I let it running mostly 24/7 hrs since 13 March 2021, and I noticed this same RPCError 400: INPUT_GZIP_INVALID error appearing a few times.

The error is not a big deal for me since in case of telegram-upload.exe exits with an error code I can retry the upload operation in an automated way (as I do in the image above), but precisely doing this it needs to start the upload from the beginning, and it consumes twice the time to upload the file, so at the end that error is very annoying.

It must be probably a connection error with the servers. Even if you have a good connection, the servers may have connection failures.

I'm afraid there is no information about that error:

There are now 3 retries per file. In case of error it will continue with the rest of the files.
