Jest on promises: triggerUncaughtException(err, true /* fromPromise */)

Question

I'm getting this error while running ALL tests (when I the only test directly that load the function involved, there's no error)

node:internal/process/promises:246
      triggerUncaughtException(err, true /* fromPromise */);
      ^

[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block,
or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason
"Error: Ha ocurrido un error, por favor intente de nuevo más tarde".] {
  code: 'ERR_UNHANDLED_REJECTION'
}

The block of code of the function that is generating the error is like this:

async getMonthRequests(rut, month) {
  try {
    // some code, in the test I'm testing that it fails
  } catch (error) {
    return Promise.reject('Ha ocurrido un error, por favor intente de nuevo más tarde');
  }
}

Any idea?
