Mocha not printing errors

I'm running async tests and the test fails silently without throwing the error.

const chai = require("chai");
var chaiAsPromised = require("chai-as-promised");
var expect = chai.expect;
chai.use(chaiAsPromised);

describe("API calls work", function () {
  it("Should have a property", function () {
    return expect(someAsyncLongRunningCall(mockedData)).to.eventually.have.property("status");
  });
});

The result returns as failed, the execution seems to stop on readFile without showing errors:

const fs = require("fs").promises;

async loadJson() {
    try {
      const jsonFile = await fs.readFile(
        "/some.json",
        "utf8"
      );

      return jsonFile;
    } catch (e) {
      console.log(e.message);
    }
  }

Am I doing something wrong? I'm running mocha like this ./node_modules/.bin/mocha --reporter spec ./tests/*.js
