When using a REST Hook trigger, the data returned by the perform must be an array.
Got a non-object result in the array, expected only objects ( )
The non-object result will be wrapped in the parentheses for the error message.
bundle.cleanedRequest
within the Perform into an array of objects.
If your webhook already provides an array, remove the wrapping array that Zapier includes by default and simply return bundle.cleanedRequest
.
