# Process flow error when using a webhook connector ## Scenario Your process flow includes a connector which is attempting to hit a webhook and the following error is displayed: ```html An Error Occurred: Unprocessable Content

Oops! An Error Occurred

The server returned a "422 Unprocessable Content".

Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

``` ## Reason This error can occur if: * The webhook connector does not include a `content-type` header * The process flow is not enabled ## Solution * Check the connector setup and ensure that header options include a `content-type` header.
