Runtime Error - something to do with Autorest

I installed it like so:
npm install -g @azure/oad

My env:
OS: MacOS Monterey 12.4

oad ver: 0.9.7

$ npm --version
6.14.16

$ node --version
v12.22.12

$ nvm --version
0.39.1

Then, tried to run the command:
**oad compare derefd.json derefd2.json**

Got:
Error: Command failed: node /Users/ananrao/.nvm/versions/node/v12.22.12/lib/node_modules/@azure/oad/node_modules/autorest/dist/app.js --v2 --input-file=derefd.json --output-artifact=swagger-document.json --output-artifact=swagger-document.map --output-file=old --output-folder=/var/folders/_v/yt6hqgc91zs8r1zzwr8g5tb80000gq/T

}

Start by reproducing `oad compare derefd.json derefd2.json` with the reported Node and oad versions, then inspect the AutoRest entry point at `node_modules/autorest/dist/app.js` and its `@autorest/core` version selection. Done means the command can locate the required core package and complete the comparison without the reported runtime error.
