'import()' expressions are not supported yet on Node engine >=14.5.0 #250

Hello,
I'm using Node 14 and all of my project is managed as a module ("type": "module" in package.json).
Until now, using everywhere imports and exports, I didn't see this error.

Lately I added a dynamic import to some new code like the following:

if(process.env.USE_NEW_CODE) {
  const { RunNewCode } = await import("./controllers/new/code.js");
  RunNewCode();
}

Suddenly I got 'import()' expressions are not supported yet error.

I have ecmaVersion field set to 2021,
and "engines": { "node": ">=14.5.0" }
According to the README of this rule, it should be enough

Node 14 fully supports ESM

Thanks in advance!
