Missing / Incorrect Definition

cause property on the Error object should have type unknown instead of Error.

Sample Code

The example from MDN:

function makeRSA(p, q) {
  if (!Number.isInteger(p) || !Number.isInteger(q)) {
    throw new Error('RSA key generation requires integer inputs.', {
      cause: { code: 'NonInteger', value: [p, q] },
    });
  }
  if (!areCoprime(p, q)) {
    throw new Error('RSA key generation requires two co-prime integers.', {
      cause: { code: 'NonCoprime', values: [p, q] },
    })
  }
  // rsa algorithm…
}

Good news: It is unknown! At least in the nightly version. This issue is a duplicate of #48098 and it has been fixed already in TypeScript 4.9.
