Hi ​@RC1101,

I was going to say that your response returns a string, but your API is probably returning JSON.

Current:

"customerName": {"type": "string","description": "The name of the customer."}


Updated.

"CustomerResponse": { "type": "object", "properties": { "customerName": { "type": "string" } }
