Hello Diogo,

If you have complex data as arrays or nested objects, you will have to convert them to JSON manually.

Why is that?

Because when making a request encoded as multipart/form-data (which is a requirement for file uploads) all you can send is a flat list of name=value pairs - where value may either be a string or a file.

If you try to add an array or an object directly to the FormData object, it will be implicitly converted to a string, which is probably not what you want (resulting in, for example, "[object Object]" or "12,15,28,55").
