Example

I am following the first example in your book for creating a form. I can configure the cloud environment OK and the form does display:

https://us-south.functions.appdomain.cloud/api/v1/web/george%40shafer.ca_dev/contact/form

When I submit the form, I get the following error:

{
"code": "a2f98a370c3e4a5a8b67dcd2c7959bf5",
"error": "There was an error processing your request."
}

I am using the code example from the book.
