Dynamic Parameters with no new elements added results into default textfield

[siddharth-ms]

Describe the Bug with repro steps

1. [Internal] Open sid-sap-testbox.ui-test in BTS4
2. Create [RFC] Call function in SAP in-app action
3. Set the Input Type to Custom
4. Then select the optional RFC Name, and set it as STFC_CONNECTION
5. A dynamicInvoke call is made which returns:

json { "response": { "body": { "type": "object", "properties": { "body": { "type": "object", "properties": { "REQUTEXT": { "type": "string", "title": "REQUTEXT", "maxLength": 1, "x-ms-visibility": "important" } }, "required": [ "REQUTEXT" ] } }, "required": [ "body" ], "default": {} }, "statusCode": "OK" } }

6. Now select the optional RFC Name, and set it as RFC_PING which doesn't need any new parameter. We want it to set body as empty object {}
7. A dynamicInvoke call is made which returns body with no parameters {}:

json { "response": { "body": { "type": "object", "properties": { "body": { "type": "object", "properties": {}, "required": [] } }, "required": [ "body" ], "default": {} }, "statusCode": "OK" } }

8. This creates a new body parameter. But we want a body parameter which has no inner parameter. basically generating body as empty object like {}

What type of Logic App Is this happening in?
