Validation failed for 1 parameter(s) error on web hook receipt

How To
1

I’ve got a scenario which is triggered by a web hook fired by my CRM. The webhook is being received by Make.com, but isn’t being processed. When I visit the logs, the web hook is arriving fine but is being treated as errored by Make.com on the grounds of the validation failing.

Here’s the blueprint for the Scenario:

There’s no error handler in place; because I can’t get the web hook to be processed by the scenario; when I go to run the scenario, the icon circles whilst awaiting for web hook data which never arrives into the scenario, even though is being received by Make when I check the web hook logs.

Does your Webhook have a Data Structure attached with Required variables?

Hope this helps! Let me know if there are any further questions or issues.
