Synchronous function execution timed out.

Hello everyone!

I know this is an old question that many of you have already asked, but I'm doing it again because I can't understand the real solution or implementation here.

I have a React Native app that calls a function like this: const execution = await functions.createExecution with async set to false, but sometimes the response takes a little longer to return, which causes the common error:

Error Code: 408``` 

My question is: How can I avoid this by using async = true and still receive an answer?

Snippet:

const result = await functions.createExecution( functionId, JSON.stringify({ audioFileId: file.$id, userId: user.$id, language }) );

router.push(/story/${storyResult.story.$id});

When I use async = true, I’m not able to get the actual payload as expected, just the current list of items / executions:

Eg:

LOG {"$createdAt": "2025-08-21T11:18:57.363+00:00", "$id": "68a700a158b4e2ba1616", "$permissions": ["read(user:68480f502aea6ab49a9c)"], "$updatedAt": "2025-08-21T11:18:57.363+00:00", "duration": 0, "errors": "", "functionId": "678cf1c9003678a4e781", "logs": "", "requestHeaders": [], "requestMethod": "POST", "requestPath": "/", "responseBody": "", "responseHeaders": [], "responseStatusCode": 0, "scheduledAt": null, "status": "waiting", "trigger": "http"} ```
