为何执行await参数的函数会报错：internalBinding('errors').triggerUncaughtException？

Question

异步调用：

initUserId().then(res => {
    console.log(res)
})

可以写成这样没错吧：

const res = await initUserId()

但是实际在执行的时候（执行npx tsx test05.ts），报错：

node:internal/process/esm_loader:40
      internalBinding('errors').triggerUncaughtException(
                                ^

Error: Transform failed with 1 error:
/Users/john/Desktop/typescript-demo-01/ts-test/test05.ts:20:12: ERROR: Top-level await is currently not supported with the "cjs" output format

请问这是什么问题呢？

完整代码如下：

const initUserId = async (): Promise<string> => {
    const fetchUserId = async(): Promise<string> => {
      // eslint-disable-next-line @typescript-eslint/no-unused-vars
      return new Promise((resolve, _reject) => {
        setTimeout(() => {
          const userId = '222';
          resolve(userId);
        }, 1000);
      })
    }
  
    const userId = await fetchUserId()
    return userId 
  }

initUserId().then(res => {
    console.log(res)
})

const res = await initUserId()

console.log(res)

export {}
