Can't upload large file because FLOOD_PREMIUM_WAIT_9 (caused by SaveFilePartRequest) keeps interrupting the upload

[doublep21]

Code that causes the issue

await client.send_file( forward, filepath, thumb=thumb, caption=caption, force_document=False, silent=True, progress_callback=lambda x, y: progress_bar(x, y, file), attributes=[ DocumentAttributeVideo(duration, videohw[0], videohw[1], False, supports_streaming=True) ] )

Expected behavior

upload a file even if i have to wait for cooldown

Actual behavior

the upload stops and i need to restart it in a infinite loop
