The function provided to the ".run" method did not resolve to a promise

Question

The function provided to the ".run" method did not resolve to a promise

Understanding the error and its reasons, I feel that my particular scenario falls outside the norm. I am implementing Word.run() within another promise structure like this:

return new Promise((resolve, reject) => {
  window.Word.run(context => {
    // perform operations with context
    resolve(someData);
  });
});

From what I gather, resolving my promise in this manner potentially leaves the .run method unresolved due to the absence of return context.sync(). Am I on the right track with my assessment? If so, how should I modify the above example to ensure proper functionality of the .run method?

Answer №1

To ensure your statement is fulfilled after the context synchronization...

return new Promise((resolve, reject) => {
  window.Word.run(context => {
    // perform operations with context
    return context.sync().then(function() {
      resolve(someData); // promise will be fulfilled after sync completion
    });
  });
});

If you do not require post-synchronization fulfillment but simply wish to synchronize the context at a later time, it can still be achieved without waiting for the sync:

return new Promise((resolve, reject) => {
  window.Word.run(context => {
    // perform operations with context
    resolve(someData); // this will fulfill the promise
    return context.sync(); // this will still occur as the function does not stop execution
  });
});
