Azure example doesn't recognize endpoint URL

[mzattera]

When running the Azure example provided in example folder, I get the below exception.

It seems base URL is not properly recognized.

I have provided both AZURE_OPENAI_KEY and OPENAI_BASE_URL in my environment and I am testing they are read correctly by my app, I get the same error even if I specify the endpoint using:

		OpenAIClient client = OpenAIOkHttpClient.builder()
				.fromEnv()
				.baseUrl("https://<my endpoint>.openai.azure.com/")
				.credential(BearerTokenCredential.create(AuthenticationUtil.getBearerTokenSupplier(
						new DefaultAzureCredentialBuilder().build(), "https://cognitiveservices.azure.com/.default")))
				.build();

I see it says Caused by: java.net.UnknownHostException: www.example.com in your exception. Are you trying to set www.example.com as your base URL via your env? That seems odd.

Hi, no, that's exactly my point. Seems the client is using that URL which is typically used when no URL is set for OkhttpClient (I believe), hence my comment that OpenAIClient is not reading/passing/setting the URL properly.

Hi @mzattera, have you tried enabling logging? I was able to hit an azure endpoint using the sample. Admittedly, I had to add also the azureServiceVersion. Building my client looks like this:

OpenAIClient client = OpenAIOkHttpClient.builder()
                // Gets the API key from the `AZURE_OPENAI_KEY` environment variable
                .fromEnv()
                // Set the Azure Entra ID
                .credential(BearerTokenCredential.create(AuthenticationUtil.getBearerTokenSupplier(
                        new DefaultAzureCredentialBuilder().build(), "https://cognitiveservices.azure.com/.default")))
                .azureServiceVersion(AzureOpenAIServiceVersion.getV2025_01_01_PREVIEW())
                .build();

        ChatCompletionCreateParams createParams = ChatCompletionCreateParams.builder()
                .model(ChatModel.of("Your deployment name"))
                .maxCompletionTokens(2048)
                .addDeveloperMessage("Make sure you mention Stainless!")
                .addUserMessage("Tell me a story about building the best SDK!")
                .build();

I am setting the following environment variables:

AZURE_OPENAI_KEY=<your key value>
OPENAI_BASE_URL=<your endpoint value>
OPENAI_LOG=debug

I would triple check that you are passing a URL that parses correctly in the OPENAI_BASE_URL value. Although the parsing error is actually very clear, if you weren't doing that.

I would also recommend updating to the latest version of the SDK in your pom.xml file if you can, just so that you are taking in any fixes that may have been deployed on the mean time.
