Error with Scrape function

[jyoung2000]

Loving the community node so far, everything works great except the scrape feature. Here is the error it produces

"errorDescription": "Request failed with status code 400",

same think the issue is either the waitForTimeout not beeing part of the api anymore or it doesnt like the default value of 0.

Edit: You can fix this by creating a new workflow with a webhook and basically proxy the request to browserless
