Cannot use optional chaining in Node 14 - syntax error?

I'm attempting to use optional chaining in my v14.17.5 NodeJS server, but get the following error whenever I use it:

/app/node_modules/babel-core/lib/transformation/file/index.js:558
      throw err;
      ^
SyntaxError: /app/src/schema/index.js: Unexpected token (64:30)
  62 |       return response;
  63 |     } catch (error) {
> 64 |       const errCode = error?.response.error.errCode === 'CannotFind' ? 404 : 500;
     |                               ^

It looks like there's an issue with the babel-core dependency, but I don't have that dependency installed, so I'm not sure what to do. I have the following babel packages installed:

"@babel/helper-hoist-variables": "^7.14.5",
"babel-cli": "6.23.0",
"babel-eslint": "10.1.0",
"babel-plugin-transform-async-to-module-method": "6.22.0",
"babel-plugin-transform-es2015-modules-commonjs": "6.23.0",
"babel-plugin-transform-flow-strip-types": "6.22.0",
"babel-plugin-transform-object-rest-spread": "6.23.0",
"babel-preset-latest": "6.22.0",
"eslint-plugin-babel": "4.0.1",

My start script is the following:

scripts {
 "start": "nodemon ./src/index.js --exec babel-node --watch ./src |       
  bunyan",
}

PS - I'm unsure what babel-node is doing here. If I could remove it some how that'd be awesome.
