QUESTION: 121

Refer to the exhibits.

A web client submits a request to the HTTP Listener and the HTTP Request throws an error.

What payload and status code are returned to the web client?

Refer to the exhibits. A web client submits a request to the HTTP Listener and the HTTP Request throws an error.

What payload and status code are returned to the web client?

Response body: "Error" Default response status code: 200
Response body: "Success - Begin* Default response status code: 200
Error response body: error, description Default error response status code: 500
Response body: "Success - End" Default response status code: 200

Answer(s): A

Explanation:

Correct Answer: Response body: "Error" Default response status code: 200. ------------------------------------------------------------------------------------------------------------------------- ------------------------
1) Payload is successfully set to "Success Started Flow"
2) When HTTP Request throws an error, execution halts
#[error.description] = "ABC"
#[error.errorType] = "XYZ"
3) The On Error Continue scope handles the error. When On Error Continue scope is invoked, all the processors in error block are executed and success response is sent back to the client with payload which is set in error flow. In this case payload is set to "Error" value in error block.
4) "Error" is returned to the requestor in the body of the HTTP request with HTTP Status Code: 200 as On error continue always sends success error code.

QUESTION: 123

Refer to the exhibits. Client sends the request to ClientRequestFlow which calls ShippingFlow using HTTP Request activity.

During E2E testing it is found that that HTTP:METHOD_NOT_ALLOWED error is thrown whenever client sends request to this flow.

What attribute you would change in ClientRequestFlow to make this implementation work successfully?

Change the method attribute value to "*''
Change the path attribute value to "/api/ship"
Change the allowed method attributes value to "POST"
Change the protocol attribute value to "HTTPS"

Answer(s): C

Explanation:

Correct answer is Change the method attributes value to "POST".
It can be fixed in either of the two ways as below.
1) Changing method attribute to POST in ClientRequestFlow
2) Setting allowedMethods as PUT in ShippingFlow (but doesn't fit as question mentions about changing ClientRequestFlow)
