Environment
I'm using the Code section of the Defender Actions web console: https://defender.openzeppelin.com/v2/#/actions/automatic
Details
I am writing an Action JS script, and getting an error on execution:
Invoke Error {"errorType":"Error","errorMessage":"API key and secret are required","stack":["Error: API key and secret are required"," at getClient (/opt/nodejs/node_modules/@openzeppelin/defender-sdk/lib/index.js:16:15)"," at Defender.get relaySigner [as relaySigner] (/opt/nodejs/node_modules/@openzeppelin/defender-sdk/lib/index.js:58:16)"," at exports.handler (/var/task/index.js:59:27)"," at Runtime.handler (/opt/nodejs/autotask-wrapper.js:101:26)"," at Runtime.handleOnceNonStreaming (file:///var/runtime/index.mjs:1173:29)"]}
I am attempting to follow the documentation and grab my relayer's API key and secret from the params OZ passes the Action at execution. Note that console.log() does seem to show that I am parsing those params correctly.
