[BUG] - by_sound() continuously returning EmptyResponseError

Describe the bug

I am trying to get tiktoks by sound using api.by_sound() method, but keep getting TikTokApi.exceptions.EmptyResponseError: Empty response from Tiktok. I have been on-and-off able to do it in the past few days, but after scraping video metadata for about 300 sounds, it tends to get stuck and just return the error anyway.

I am using custom_verifyFp and use_test_endpoints=True. In addition, I have used various VPNs, resolved captcha, deleted cookies, etc. I have confirmed that the sound in question exists, and have tried many different sounds to confirm the issue persists.

The buggy code

api = TikTokApi.get_instance(custom_verifyFp = my_fp, use_test_endpoints=True)

videos_by_sound = api.by_sound('7004098435989162758', count=2000, custom_did=str(random.randint(10000, 999999999)), custom_verifyFp = my_fp, use_test_endpoints=True)

Expected behavior

Returned JSON with tiktoks.
