Description

We occasionally see failed auth0 requests due to "socket hang up" - it causes our app's flow to break as we didn't expect this is something that needs handling.

The existing retry implementation can only handle failed requests based on statusCode, which does not apply in this case:

node-auth0/src/lib/retry.ts

Lines 66 to 70 in 17bac36

	result = await action();
	if ((retryWhen || [429]).includes(result.status) && nrOfTries < nrOfTriesToAttempt) {
	nrOfTries++;

Expectations:

• Allow retrying on "socket hang up" and possibly other network related errors
• Provide new defaults for Retry, including "socket hang up"

APIError: socket hang up

Reproduction

1. I cannot think of an easy reproduction - probably needs some fault injection/mocking to trigger it easily.

Sample code:

export const authClient = new AuthenticationClient({
  domain: config.domain,
  clientId: config.clientId,
  clientSecret: config.clientSecret,
});

await authClient.passwordGrant({
      username: user_email,
      password: user_password,
      audience: config.audience,
    });
