how to list Api Management Services with java sdk and trouble shoot com.azure.core.implementation.http.rest.MissingRequiredAnnotationException

Question

I try to access API Management Service with Java SDK (Kotlin Syntax). First of all I just want to list all the services in my Java Code. I imported the following libries:

implementation("com.azure:azure-core:1.39.0") // https://mvnrepository.com/artifact/com.azure/azure-core
implementation("com.azure:azure-security-keyvault-secrets:4.6.1") // https://mvnrepository.com/artifact/com.azure/azure-security-keyvault-secrets
implementation("com.azure:azure-identity:1.9.0") // https://mvnrepository.com/artifact/com.azure/azure-identity
implementation("com.azure:azure-core-management:1.11.1") //https://central.sonatype.com/artifact/com.azure/azure-core-management/1.11.1?smo=true
implementation("com.azure.resourcemanager:azure-resourcemanager-apimanagement:1.0.0-beta.3") // https://central.sonatype.com/artifact/com.azure.resourcemanager/azure-resourcemanager-apimanagement/1.0.0-beta.3?smo=true
implementation("com.azure.resourcemanager:azure-resourcemanager-authorization:2.26.0") // // https://mvnrepository.com/artifact/com.azure.resourcemanager/azure-resourcemanager-authorization
implementation("com.azure:azure-identity-providers-core:1.0.0-beta.1") //https://central.sonatype.com/artifact/com.azure/azure-identity-providers-core/1.0.0-beta.1?smo=true
implementation("com.azure:azure-identity-extensions:1.1.3") // https://central.sonatype.com/artifact/com.azure/azure-identity-extensions/1.1.3?smo=true

and the code looks like this (Kotlin)

val profile = AzureProfile(TENANT_ID, SUBSCRIPTION_ID, AzureEnvironment.AZURE)

val clientSecretCredential = ClientSecretCredentialBuilder()
    .clientId(CLIENT_ID)
    .clientSecret(CLIENT_SECRET)
    .tenantId(TENANT_ID)
    .authorityHost(profile.environment.activeDirectoryEndpoint)
    .build()

val manager = ApiManagementManager.authenticate(clientSecretCredential, profile)

val l = manager.apiManagementServices().list()
println("API Management Services found:")
l.mapPage { service ->
    println("Name: " + service.name())
    println("Location: " + service.region())
    println("Sku: " + service.sku().name())
    println("Provisioning State: " + service.provisioningState())
}

TENANT_ID, CLIENT_ID, CLIENT_SECRET and SUBSCRIPTION_ID are tested with the curl request and work just fine with curl. I can list all API Management Services. The App has the rights.

The Problem Happens here:

ApiManagementServicesClientImpl(ApiManagementClientImpl client) {
    this.service =
        RestProxy
            .create(ApiManagementServicesService.class, client.getHttpPipeline(), client.getSerializerAdapter());
    this.client = client;
}

The service ends up with:

Method threw 'com.azure.core.implementation.http.rest.MissingRequiredAnnotationException' exception. Cannot evaluate com.azure.resourcemanager.apimanagement.implementation.$Proxy32.toString()

Wich Annotation do I miss? I imported client and management core libraries. Can someone help me with this mystery.

I tried different libraries, different keys, test api call with curl using same the credentials, which worked

Thanks

The exception you're encountering, MissingRequiredAnnotationException, indicates that a required annotation is missing. In this case, it seems to be related to the toString() method in the ApiManagementServicesClientImpl class.

To troubleshoot this issue, you can try the following steps:

Check dependencies: Make sure you have the necessary dependencies and versions correctly configured. Ensure that the versions of the Azure SDK libraries are compatible with each other.

Verify compatibility: Confirm that the versions of the Azure SDK libraries you're using are compatible with the version of Azure API Management you're trying to access. It's possible that there might be incompatibilities between the Azure SDK and API Management versions.

Review code implementation: Double-check your implementation of the ApiManagementServicesClientImpl class. Ensure that you've correctly imported the required classes and that the necessary annotations are present. Compare your implementation with official Azure SDK documentation and examples to ensure you're following the correct structure and annotations.

Update library versions: Consider updating the versions of the Azure SDK libraries you're using to the latest stable versions. Newer versions often contain bug fixes and improvements that may address the issue you're facing.

Check Azure SDK GitHub repository: Visit the GitHub repository for the Azure SDK for Java (https://github.com/Azure/azure-sdk-for-java) and search for similar issues or error messages. It's possible that someone else has encountered a similar problem and has posted a solution or workaround.

Contact Microsoft Azure support: If the issue persists and you're unable to find a solution, it may be beneficial to contact Microsoft Azure support. They can provide further assistance and investigate the issue in more detail.

Remember to provide relevant information, such as the full stack trace of the exception, specific library versions, and any other relevant code or configuration details when seeking support or reporting the issue.
