Rclone copy with tqdm progressbar issue

I am new to Python programming and am currently working on a telegram bot that will download a file from YouTube and upload it to Google drive. I am facing a problem with one part of the code.

def rclonecopyprocess(bot_msg, paths):
RCLONE_PATH = '/usr/bin/rclone'
cmd = [
    RCLONE_PATH,
    'copy',
    paths,
    'PD:/tele',
    '--progress',
    '--drive-chunk-size=16M',
    '--transfers=16',
    '--checkers=16',
    '--buffer-size=64M',
    ]
checkfiles=[
    RCLONE_PATH,
    'check',
    paths,
    'PD:/tele',
    '--one-way',
    '-P',
    ]
proch = Popen(checkfiles, stdout=PIPE, bufsize=1, universal_newlines=True,text=True)
for line in proch.stdout:
    line=line.strip()
    if '0 differences found' in line:
        edit_text(bot_msg,'File Present in the cloud ☁')
        proch.kill()
        return
    else:
        pbar=tqdm(total=100, desc="Uploading to cloud ☁:", ncols=80,ascii="░▒",unit = 'B')
        proc = Popen(cmd, stdout=PIPE, bufsize=1, universal_newlines=True,text=True)
        for line in proc.stdout:
            line = line.strip()
            if line.startswith('*'):
                percent = int(line.split(':')[1].split('%')[0])
                if percent<100:
                    pbar.n = percent
                    pbar.refresh()
                    edit_text(bot_msg, pbar)
                else:
                    edit_text(bot_msg,'Upload Finished!✅')
                    proc.kill()
                    return

The problem i am getting is "ValueError: invalid literal for int() with base 10:" this error whenever the video file size is small. I don't get any such error for large files.
