I have written code to call Fetch method to Post Json file to IPFS .
I am writing the JSON file locally which succeds , but later when i call the POST method using FORMDATA to write json file to IPFS it fails.
Same code works fine on iOS . Not sure what is the issue with Android.

Also tried using IP of the server , using xmlhttprequest , different options for setting cors/no-cors etc but still getting the same error .

I am using Android version 8.0, Reactnative version 0.57 and "react-native-fs": "^2.13.3".
Can somebody suggest an alternate way to make network calls.Cant use native code as this code is in JS library.Kindly provide your valuable feedback.
Below is the code snippet :

justcall(valueToWrite)
 var path = RNFS.DocumentDirectoryPath + '/writeddo.json';
 //var path = RNFS.LibraryDirectoryPath + '/writeddo.json';
 console.log("path",path);
 return new Promise((resolve, reject) => 
 // write the file
 RNFS.writeFile(path, valueToWrite,'utf8')
 .then((success) => 
 console.log('FILE WRITTEN!');
 let formdata = new FormData();
 formdata.append('file', 
 uri: path,
 name: 'writeddo.json',
 type: 'multipart/form-data'
 );
 console.log("formdata",formdata);
 console.log("IPFSADD Url",IPFSADD);

 fetch(IPFSADD, 
 method: 'POST',
 headers: 
 // 'Accept': 'application/json',
 'Content-Type': 'multipart/form-data',
 ,
 //mode: "no-cors", //, cors, *same-origin
 body: formdata
 )
 // .then((serviceResponse) => return serviceResponse.json() ) 
 .then((serviceResponse) => 
 console.log("Justcall response", serviceResponse);
 return this.deleteJsonFile(path).then(() => 
 resolve(serviceResponse)
 )
 .catch((error) => 
 console.error("Error while deleting the file error:", error)
 reject(new Error(error))
 )
 )
 .catch((error) => 
 console.error("fetch error:", error)
 reject(new Error(error))
 )

 ) // Write File
 .catch((err) => 
 console.log("Error while writing file locally" +err.toString());
 reject(new Error(err))
 );
 ) //Promise
