How can I recovery from the error 9030 while mailbox.item.body.getAsync failed?

Question

I'm working on the outlook add-in. But I get the issue that sometimes Office.context.mailbox.item.body.getAsync will failed when the add-in page reloaded. The worst thing is that, once body.getAsync return the error "APICallFailedDueToItemChange", the body.getAsync will be always failed with the same error. The detail of this error is {name: "APICallFailedDueToItemChange", message: "The selected item has been changed.", code: 9030}

I tried to recall the getAsync and even reload the whole window to make the add-in restarted, but the error will happen persistently. The only way is switching to another email.

Reproduce steps: 1. Create any outlook add in which try to get the email body 2. after add-in loaded, reload the add-in window 3. Once the 9030 error happened, those code in console will always trigger the same error until I switch to another email

await new Promise((resolve, reject) => {
    window.Office.context.mailbox.item.body.getAsync('text', (result) => {
      if (result.status === 'succeeded') {
        console.log(result.value)
        return resolve(result.value); // updated as suggested by Mavi Domates
      } else {
        console.error(result.error)
        return reject(result.error);
      }
    })
  })

I expect the getAsync should work fine even the previous callback is failed, but actual the exception will never be cleaned.

Please modify your code as such, you aren't really doing anything with that promise.

await new Promise((resolve, reject) => {
    return window.Office.context.mailbox.item.body.getAsync('text', (result) => {
      if (result.status === 'succeeded') {
        console.log(result.value);
        return resolve(result.value);
      } else {
        console.error(result.error);
        return reject(result.error);
      }
    })
  })
