Cannot get ts-node to compile code with optional chaining

Question

Why does it do that? I thought I had it working, but after writing some code with ?. syntax in it, it stopped working. I tried to update involved dependencies but to no avail.

Bellow is hopefully everything relevant. (Command is npm run generate:nexus)

package.json

{
  "name": "rita",
  "version": "0.0.0",
  "license": "MIT",
  "scripts": {
    ...
    "generate:nexus": "ts-node --transpile-only --project=./apps/server/tsconfig.nexus.json ./apps/server/src/nexus-prisma/schema.ts"
  },
  "dependencies": { ... },
  "devDependencies": { 
    ...
    "ts-node": "~9.1.0"
  },
}

tsconfig.nexus.json

{
    "extends": "./tsconfig.json",
    "compilerOptions": {
        "baseUrl": ".",
        "module": "CommonJS",
        "target": "esnext",

        "outDir": "dist",
        "rootDir": "src",
        "lib": ["esnext"],
        "esModuleInterop": true,
        "strict": true,
        "typeRoots" : [
            "node_modules/@types",
            "./src/nexus-prisma/nexus.generated.ts",
        ],

        //"extendedDiagnostics": true,
        //"noEmit": true,
    },
    "files": [
        "./src/nexus-prisma/schema.ts",
    ],
}

Error:

ts-node --transpile-only --project=./apps/server/tsconfig.nexus.json ./apps/server/src/nexus-prisma/schema.ts

tldr; It is not TS error but a runtime nodeJS error. The target must be `es2019` or lower. — Akxe, Jan 05 '21 at 06:59

There were no compiling errors, the error was that the node used did not support .? optional chaining.
