An API client is implemented as a Mule application that includes an HTTP Request operation using a default configuration. The HTTP Request operation invokes an external API that follows standard HTTP status code conventions, which causes the HTTP Request operation to return a 4xx status code.
What is a possible cause of this status code response?
A 4xx status code indicates a client error, which means that the external API reported an issue with the request it received from the Mule application. This can include problems such as a bad request (400), unauthorized access (401), forbidden access (403), or the requested resource not being found (404). Therefore, the most likely cause is that the external API reported an error with the HTTP request that was received from the outbound HTTP Request operation of the Mule application.
It has to be B Cannot be D cause resource moved will be 301 error code.. Cannot be C because http resonse cannotbe interpreted does not cause 4xx unless there is mapping created on HTTP connector. Cannot be A cause error inside external API should generate 5xx errors.
B Should be the correct answer
It should be B
B. The external API reported an error with the HTTP request that was received from the outbound HTTP Request operation of the Mule application
It has to be B
4xx client error – the request contains bad syntax or cannot be fulfilled
