Describe the bug

the definition of headers was changed on 97cefc8#diff-d5aa9217e2132932fec24cba8c2a103430c34ed925739a4529a0acd16483803aR8246

While the API still return in the original format:

                    "headers": {
                        "authorization": {
                            "type": "Expression",
                            "value": "@pipeline().parameters.test"
                        },
                        "content_type": "application/x-www-form-urlencoded"
                    }

which does not match the Swagger

Expected behavior

Actual behavior

Reproduction Steps
