Troubleshooting

Error Handling

Our generated clients raise errors when a service cal returns an undesired error code.

A very basic form of error handling looks like this

import { DefaultAzureCredential } from "@azure/identity";
import { PetsClient } from "@azure/pets";

const client: PetsClient = new PetsClient(new DefaultAzureCredential());
try {
    const dog = await client.getDog();
} catch (err) {
    console.log(err.statusCode);
}

Logging

Enabling logging may help uncover useful information about failures. In order to see a log of HTTP requests and responses, set the AZURE_LOG_LEVEL environment variable to info.

export AZURE_LOG_LEVEL=info

For more detailed instructions on how to enable logs, you can look at the [@azure/logger package docs][logger-docs]
