这里出了什么问题？我试图在一个枚举类型的数组中找到一个枚举值。但是TS抱怨了，正如你所看到的。

export enum LearningStageType {
  FUEL_DOOR_OFFSET = 'FUEL_DOOR_OFFSET',
  VEHICLE_INFO = 'VEHICLE_INFO',
  POSITIONING = 'POSITIONING',
  CYCLE_DRY_RUN = 'CYCLE_DRY_RUN',
  FINISH = 'FINISH',
}

// Type of `status` used below
export interface LearningStatus {
  vehicleId: string;
  licensePlate: string;
  countryCode: ISO3166a2CountryCode;
  // ...
  allowedStages?: LearningStageType[];

}

// Type of `stage` in code below
export type LearningStage = {
  stageType: LearningStageType;
  instructionText: string;
  instructionImage?: ImageSourcePropType;
  title: string;
  subtitle?: string;
  mainComponent: React.FC<LearningStageProps>;
  isAllowed?(status: LearningStatus, settings: LearningSettings): boolean;
};

// My code
  const stage = stages[previousStageType];

  if (skipValidation) {
    return stage;
  }
  if (stage.isAllowed) {
    return stage.isAllowed(status, settings) ? stage : null;
  }
  // The line that makes TS complain:
  if (status.allowedStages?.includes[stage.stageType]) {
    return stage;
  }
  return null;

TS错误：

(property) LearningStatus.allowedStages?: LearningStageType[] | undefined
Element implicitly has an 'any' type because expression of type 'LearningStageType' can't be used to index type '(searchElement: LearningStageType, fromIndex?: number | undefined) => boolean'.
  Property '[LearningStageType.FUEL_DOOR_OFFSET]' does not exist on type '(searchElement: LearningStageType, fromIndex?: number | undefined) => boolean'.ts(7053)
