multipart != application/x-www-form-urlencoded

On iOS i don’t have any problems.

Running the app for the first time on Android.

Two times I do a fetch:

    const data = new FormData();
    ......

    fetch('........', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/x-www-form-urlencoded'
      },
      body: data
    })

Can’t find anything about this error…

I just ran across this same issue. I was able to get around it by changing the Content-Type header.

When I was getting the error I had:

'Content-Type': 'application/x-www-form-urlencoded'

And when I switched it to this it worked:

'Content-Type': 'multipart/form-data'

Hope this helps anyone else who runs into this issue later on.

Hi, as @jasonmerino said, you have to set ‘Content-Type’: ‘multipart/form-data’ and specify the type of your file like this: const data = new FormData(); data.append('image', { uri: source, name: 'image', type: 'image/png' });
