I noticed prettier is coming from jest-snapshot in package-lock.json:

    "node_modules/jest-snapshot": {
      "version": "26.6.2",
      "resolved": "https://registry.npmjs.org/jest-snapshot/-/jest-snapshot-26.6.2.tgz",

      "dependencies": {

    },

Any ideas?

I faced the issue from one moment to another and looks like this is the problem https://github.com/aws/aws-cdk/issues/20319

the suggested solution to add a fixed version of prettier to the Dev dependencies worked for me. Give it a try

{
  "devDependencies": {
    "@types/prettier": "2.6.0"
  }
}

if you're using projen for scafolding the change should be in the projen.js file

devDeps: [
    '@types/[email protected]'
]
