What does a 422 HTTP error on a webhooks page mean?

[jawel]

Can't connect BitBucket to DeployHQ. 
When opening the webhook url, the page displays. But when something is pushed to the repo, no auto-deploy is taking place.
Could you please help out?
Kind regards,

Hey Jan-Willem van Veelen,

I did some dig regarding this error and found some things which you can test in your instance to see if its the same problem:

Take a look at the comments there, hope it helps!
