[danohn]

Description

When running the Quickstart and requesting an Access Token from e.g. https://quickstart-1234-dev.twil.io/access-token, an error is returned with the following message:

{
  "message": "identity is required to be specified in options",
  "name": "Error",
  "stack": "Error: identity is required to be specified in options\n    at new AccessToken (/var/task/node_modules/twilio/lib/jwt/AccessToken.js:28:19)\n    at exports.handler (/var/task/handlers/ZNf10e7cbc86844358c2a38dee2f1bd9a4.js:18:17)\n    at exports.handler (/var/task/node_modules/runtime-handler/index.js:339:10)\n    at exports.handler (/var/task/runtime-handler.js:17:17)\n    at Runtime.handleOnceNonStreaming (file:///var/runtime/index.mjs:1173:29)"
}

Steps to Reproduce

1. Clone the repo
2. Copy the .env.example file and update the .env file as needed
3. Run the twilio serverless:deploy command
4. Attempt to retrieve an Access Token from e.g. https://quickstart-1234-dev.twil.io/access-token

Expected Behavior

The function should mint an Access Token

Actual Behavior

The function returns the error:

{
  "message": "identity is required to be specified in options",
  "name": "Error",
  "stack": "Error: identity is required to be specified in options\n    at new AccessToken (/var/task/node_modules/twilio/lib/jwt/AccessToken.js:28:19)\n    at exports.handler (/var/task/handlers/ZNf10e7cbc86844358c2a38dee2f1bd9a4.js:18:17)\n    at exports.handler (/var/task/node_modules/runtime-handler/index.js:339:10)\n    at exports.handler (/var/task/runtime-handler.js:17:17)\n    at Runtime.handleOnceNonStreaming (file:///var/runtime/index.mjs:1173:29)"
}

Fix

As per This Stack Overflow answer, with version 4 and above of the Node.js client (the current default for serverless functions is 5.0.3), you now need to supply an identity property in the AccessToken config. For example:

  const token = new AccessToken(
    twilioAccountSid,
    twilioApiKey,
    twilioApiSecret,
    { identity }
  );
  token.addGrant(voiceGrant);
  // token.identity = identity;
