ERROR: cannot use import statement outside module - node.js

Question

Have seen posts like this before but none of the fixes have worked for me. I am trying to use the firebase emulator and having issues building firebase functions. When building and running the app all works okay, just having issues with modules in my functions.
Here is the error output I'm getting:
SyntaxError: Cannot use import statement outside a module

! We were unable to load your functions code. (see above)
> (node:3540) Warning: require() of ES modules is not supported.
> require() of C:\Users\abiga\Desktop\communityX\node_modules\node-fetch\src\index.js from C:\Users\abiga\Desktop\communityX\functions\index.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
> Instead rename C:\Users\abiga\Desktop\communityX\node_modules\node-fetch\src\index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from C:\Users\abiga\Desktop\communityX\node_modules\node-fetch\package.json.
I have tried the 3 suggestions given (using import, removing type module, and switching to .cjs) but similar errors continue in all cases. Other devs have same code and node version (12.15.0) so not sure why only I am getting errors. Any help is much appreciated!!
Here is my package.json file for functions:
"name": "functions",
"description": "Cloud Functions for Firebase",
"scripts": {
"serve": "firebase emulators:start --only functions",
"shell": "firebase functions:shell",
"start": "npm run shell",

And here is the package.json file for the module giving the issues (node-fetch).
