Sending FormData through client.mutate()

[pranaybinju]

Is there any way I can send FormData through client.mutate() ? I have a file which needs to be sent as FormData to backend as POST request. We are using a wrapper function over client.mutate() to send file, but it is sent as blank object, seems due to JSON.stringify present inside the mutate function applied to data.

Would be helpful if you can suggest a way for it.
