Before You File a Proposal Please Confirm You Have Done The Following...

• I have searched for related issues and found none that match my proposal.
• I have searched the current rule list and found no rules that match my proposal.
• I have read the FAQ and my problem is not listed.

My proposal is suitable for this project

• I believe my proposal would be useful to the broader TypeScript community (meaning it is not a niche proposal).

Link to the rule's documentation

https://typescript-eslint.io/rules/prefer-promise-reject-errors/

Description

Similarly to the options of only-throw-error, the following should be available for prefer-promise-reject-errors, possibly turned on in an upcoming major version by default:

• allowThrowingAny
• allowThrowingUnknown

Fail

async function demo() {
  try {
    throw new Error();
  } catch (error: unknown) {
    /* eslint @typescript-eslint/prefer-promise-reject-errors: "error" */
    return await Promise.reject(error);
  }
}

Pass

async function demo() {
  try {
    throw new Error();
  } catch (error: unknown) {
    /* eslint @typescript-eslint/prefer-promise-reject-errors: ["error", { allowThrowingUnknown: true }] */
    return await Promise.reject(error);
  }
}
