Unable to Catch ApiRequestException for 429 (Too Many Requests)

I found a bug to report

Please use the following template to ensure maintainers can reproduce the bug and solve it quickly.

Bug reports that do not follow this template will be kept closed because not-reproducible until the creator edits the post properly.

Steps to reproduce

try
{
    // Send 100 text messages to a group chat
    for (int i = 0; i < 100; i++)
        await Bot.SendTextMessageAsync(chatId, "Hello");
}

catch (ApiRequestException e)
{
    // Retry after the wait time
    await Task.Delay(e.Parameters.RetryAfter);
    await Bot.SendTextMessageAsync(chatId, "Hello");
}

Expected behavior

I expect to catch ApiRequestException so that I can get the retry_after ResponseParameter.

Actual behavior

HttpRequestException is thrown, which doesn’t include the retry_after ResponseParameter. So I have no way of knowing how long I should wait before retrying.

@kirsan31 It will be fixed only in the next major release since fixing it is a breaking change in terms of runtime behaviour. You’ll have to wait for it.
