I used the ready to use template “Transform new orders from WooCommerce to Offline events in Facebook” for month without any issues, but from one day to another it stopped working. The error is: The operation failed with an error. Function ‘createBody’ finished with error! The “data” argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received null
same error when using shopify version of this scenario:
“Function ‘createBody’ finished with error! The “data” argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received null”
