async postFileUpload(payload) {
    const rnfetchfile = RNFetchBlob.wrap(payload.uri);
    try {
    console.log(
        'POST',
        'https://******.***.**/******/***/upload_*******_file',
        {
          ...this.config,
          'Content-Type': 'multipart/form-data',
        },
        [
          // element with property `filename` will be transformed into `file` in form data
          {
            name: 'files',
            filename: payload.name,
            data: rnfetchfile.replace('file://file:///', 'file://'),
          },
        ],
      );
      const res = await RNFetchBlob.fetch(
        'POST',
        'https://******.***.**/******/***/upload_*******_file',
        {
          ...this.config,
          'Content-Type': 'multipart/form-data',

        [
          // element with property `filename` will be transformed into `file` in form data
          {
            name: 'files',
            filename: payload.name,
            data: rnfetchfile.replace('file://file:///', 'file://'),
          },
        ],
      );
    const response = JSON.parse(res.data);
      console.log('api upload adpostimage', response);
      return response;

as here said just use decodeURIComponent(uri)

this is my code :

const realPath = Platform.OS === 'ios' ? uri.replace('file://', '') : uri;

const data = [
  {
     name: 'file',
     filename,
     type,
     data: RNFetchBlob.wrap(decodeURIComponent(realPath)),
  },
  {name: 'bla', data: 'bla'}
]

Try replacing the file://file:// to '' an empty string.. 

rnfetchfile.replace('file://file:///', '')

– @Abhishek Ghosh commented is a need trick which will work but the file will not be available in the uri.. your uploaded file wont open

I tried doing 

data: decodeURIComponent(rnfetchfile.replace('file://file:///', 'file:///')

and it worked hope this helps
