unexpected end of stream

when I called api/rooms.upload with restapi, continuous call in ReactNative use RNFetchBlob, it respond Stream Closed.
Rocket.Chat 5.4.5
React Native 0.71.5

RNFetchBlob.fetch(method, url, headers, formData)
.then(res => {
store.dispatch({
type: 'SET_ISLOADING',
data: false,
});
res.flush();
})
.catch(err => {
store.dispatch({
type: 'SET_ISLOADING',
data: false,
});
console.log(err);
Toast.info({ content: 'upload error', duration: 1 });
});

Start by reproducing the continuous api/rooms.upload call using React Native 0.71.5 and RNFetchBlob against Rocket.Chat 5.4.5, then trace where the response reports "Stream Closed." Done means identifying and fixing the unexpected end-of-stream behavior and confirming repeated uploads complete successfully.
