Error received from Telegram GetUpdates Request: null: Telegram API error details being masked by bad exception handling

Describe the bug

I'm currently getting the following stacktrace:

2024-11-04 07:27:28,201 ERROR [pool-4-thread-1] o.t.t.l.BotSession - [] Error received from Telegram GetUpdates Request, retrying in 269 millis...

Expected behavior

If the Telegram API responds with a non-2xx status code, I should be able to see error details. When the API response is unsuccessful, a TelegramApiErrorResponseException containing the status code and message is thrown. However, this exception is immediately caught and wrapped in an instance of itself, with the code simply being overwritten/nulled, as can be seen here.

Additional context

Something like this shows up in #1401 as well, it seems.

I'll do some experiments with a fork of this project to see if I can make some progress on this myself. I just wanted to have this issue tracked in case other people run into it as well.

Addressed by #1453.
