Troubleshooting the Azure JavaScript SDK
Find solutions to the most common issues developers encounter when using the Azure JavaScript SDK.
Authentication failures (401/403)▼
Typical causes:
- Incorrect client ID/secret.
- Expired token.
- Missing required scopes.
Example: Refreshing a token using @azure/identity:
import { DefaultAzureCredential } from "@azure/identity";
const credential = new DefaultAzureCredential();
async function getToken() {
const token = await credential.getToken("https://management.azure.com/.default");
console.log(token.token);
}
getToken();Network timeouts and retries▼
Configure retry policies using @azure/core-http:
import { ServiceClient } from "@azure/core-http";
const client = new ServiceClient(credentials, {
retryOptions: {
maxRetries: 5,
retryDelayInMs: 2000
}
});Ensure your environment allows outbound traffic on ports 443 and 80.
Incorrect API version errors▼
Always specify the latest stable API version or let the SDK handle it:
import { ComputeManagementClient } from "@azure/arm-compute";
const computeClient = new ComputeManagementClient(credential, subscriptionId);
await computeClient.virtualMachines.beginCreateOrUpdate(resourceGroup, vmName, {
location: "eastus",
// No explicit apiVersion needed; SDK picks the right one.
});
