iOS: RNFetch.fetch upload file [The network connection was lost ]

QAZDER commented 3 years ago

Hi, when using RNFetch.fetch to upload images which selected by react-native-image-picke, it got an error on ios: The network connection was lost. it works fine on android.

is there any config i didn't add to header? thanks in advance!

here is my code:

  const header = {
    Authorization: 'Bearer ' + window.token,
    'Content-Type': 'multipart/form-data'
  }; 

  const bodyData = [{
    name: 'file',
    filename: item.fileDesc || item.fileName,
    data: RNFetchBlob.wrap(item.uri)
  }];

 return (RNFetchBlob.fetch('POST', uploadUrl, header, bodyData));

Version:

    "react": "16.8.6",
    "react-native": "0.60.4",
    "rn-fetch-blob": "^0.12.0",

Well its returning a promise, so you should probably have RNFetchBlob.fetch(...).then(...) or use async/await. If you're not awaiting the promise its possible that it never does its work properly without an await.

Thanks for the reply. But I don't think this error is caused by async/await cause this error only happens when bodydata is an array, while it works fine when bodydata is an object.
