Description
Hello everyone. Currently I am working on contribution for the get() operation for applicatons. The essence of contrubution is to migrate client implementation from v2 CF APIs to v3. In DefaultApplications Java class this method is used for getting Application details:
private static Mono<ApplicationInstancesResponse> getApplicationInstances(CloudFoundryClient
cloudFoundryClient, String applicationId) {
return requestApplicationInstances(cloudFoundryClient, applicationId)
.onErrorResume(ExceptionUtils.statusCode(CF_BUILDPACK_COMPILED_FAILED, CF_INSTANCES_ERROR,
CF_STAGING_NOT_FINISHED, CF_STAGING_TIME_EXPIRED, CF_STAGING_ERROR),
t -> Mono.just(ApplicationInstancesResponse.builder().build()));
}
Here we see the handling of various errors by their status codes. Method ExceptionUtils.statusCode just checks if at least one of the passed codes to this method matches the code returned from the API of the V2.
In the DefaultApplications defined following status codes:
private static final int CF_APP_STOPPED_STATS_ERROR = 200003;
private static final int CF_BUILDPACK_COMPILED_FAILED = 170004;
private static final int CF_INSTANCES_ERROR = 220001;
private static final int CF_SERVICE_ALREADY_BOUND = 90003;
private static final int CF_STAGING_ERROR = 170001;
private static final int CF_STAGING_NOT_FINISHED = 170002;
private static final int CF_STAGING_TIME_EXPIRED = 170007;
I want to ask a question where the list of these codes was taken from?
(I tried to find them in the CF API V2 documentation but didn't find them unfortunately.).
Also, do we have similar list of errors for CF V3 APIs? If we have could please share with me some sources, where I can find them? (I tried to find them there: https://v3-apidocs.cloudfoundry.org/version/3.131.0/index.html#errors) But it is common information about the errors and there we don't have info about the returning errors for a specific API endpoint.
