[Bug]: v1/video/caption endpoint does not work if you add webhook url

[abdullahbt]

Describe the bug

I've been trying to get the captions endpoint to work for days. The response never reached webhook and Google Logs never stopped at "warnings.warn("FP16 is not supported on CPU; using FP32 instead")". Finally saw a youtube video and the guy was doing it without a webhook URL so I removed the webhook url from payload, keeping everything else the same, and the request went through. I was using a Make.com webhook which I confirmed was working

Reproduction Steps

Sent the following payload:
{
"video_url": "https://storage.googleapis.com/my-bucket/my-video.mp4",
"settings": {
"line_color": "#FFFFFF",
"word_color": "#FFFF00",
"outline_color": "#000000",
"all_caps": false,
"max_words_per_line": 10,
"position": "bottom_center",
"alignment": "center",
"font_family": "Arial",
"font_size": 24,
"bold": false,
"italic": false,
"style": "karaoke",
"outline_width": 2,
"shadow_offset": 2
},
"replace": [
{
"find": "um",
"replace": ""
},
{
"find": "like",
"replace": ""
}
],
"webhook_url": "https://hook.eu2.make.com/my-webhook",
"id": "request-123",
"language": "en"
}
