useObject error: [Error: The response body is empty.]

[sgandon]

Hello
I am trying to use the Vercel ai-sdk in order to extract specific fields values (first-name, last-name, sex) from a set of patients.
I am developing an Expo app (quite advanced right now) and try to integrate this AI sdk for importing patients into it.
I have extracted my code to show it in a reproducable way here, in order to run it it requires an .env.local set with the env-var EXPO_PUBLIC_OPENAI_API_KEY, and an update of the server url).

Server side

I have developed a server side API here and it seems to be working at least when I do a curl.

curl -X POST http://localhost:8082/api/extract-patients
[{"firstname":"Mildred","lastname":"Hudson","male":false},{"firstname":"WALTER","lastname":"MYERS","male":true},{"firstname":"Eugene","lastname":"Cook","male":true},{"firstname":"Pamela","lastname":"Owens","male":false}]

but the client fails.

client side

I just implemented a simple client using useObject here and it is failing with the following error

 ERROR  === useObject ERROR ===
 ERROR  useObject error: [Error: The response body is empty.]

The call seem to be waiting for the end of the payload (so the isLoading is working). But I would like to have streaming of each object. The object returned seems to be never filled with the data.
And it eventually fails at the end.

Any help would be much appreciated.

Thanks.
