getCodeFixesAtPosition returns an empty array of codefixes without throwing an error.

More minimal:

export class Something {
  constructor() {
    this.blah({
      'thingy01': '',
      'thingy02': '',
      'thingy03': '',
      'thingy04': '',
      'thingy05': '',
      'thingy06': '',
      'thingy07': '',
      'thingy08': '',
      'thingy09': '',
      'thingy10': '',
      'thingy11': '',
      'thingy12': '',
      'thingy13': '',
      'thingy14': '',
      'thingy15': '',
      'thingy16': '',
    });
  }
}

or even

foo({
  thing001: '',
  thing002: '',
  thing003: '',
  thing004: '',
  thing005: '',
  thing006: '',
  thing007: '',
  thing008: '',
  thing009: '',
  thing010: '',
  thing011: '',
  thing012: '',
  thing013: '',
  thing014: '',
  thing015: '',
  thing016: '',
});
