Why does this error appear when running Nrwl nx cli?

I've been trying to learn and use the nwrl nx framework in creating a new mono repo with angular applications. However, when trying to use the nx cli for any commands, I get the following error:

    at JSON.parse (<anonymous>)
    at Object.parseJsonWithComments (/Users/bendunc/Documents/MTC Apps/mtc-language/node_modules/@nrwl/workspace/src/utils/fileutils.js:43:17)

(node:5280) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

I get this error whenever I run an nx command such as

nx serve <app name>

or

npx ng serve <app name>

I've tried uninstalling and reinstalling the nx cli to no avail. Any help or suggestion would be much appreciated

Thank you.

A colleague helped me solve the issue. The problem was a trailing comma in my tsconfig.json file and JSON doesn't allow for trailing commas. So, if you've got a similar error, make sure that your main JSON files in your nx/angular project are properly formatted.
