Hi there,
I am trying to create webhooks to receive requests when a file is updated but when I send the request, it hangs for 2min and then I see the error:
```
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

If you provide content to customers through CloudFront, you can find steps to troubleshoot and help prevent this error by reviewing the CloudFront documentation.

The request is structured like the following:
POST - https://api.figma.com/v2/webhooks
Body:
```
{
"event_type": "FILE_UPDATE",
"context": "file",
"context_id": "<file id>",
"endpoint": "<lambda url>",
"passcode": "<passcode>"
}
```
I can ensure the lambda has no auth and returns a 200 http code in less than a second.
Can you help me understand what I am missing?
