React-admin: How to send a multipart data

[sbatururimi]

Hi. Can you show an example of a multipart file upload? I'm trying the following which fails:

const addUploadCapabilities = requestHandler => (type, resource, params) => {
    if (type === 'CREATE' && resource === 'books') {
        // console.log(params.data.files);
        if(params.data.files){
             const files = params.data.files.map(file => file.rawFile)
            const coverFile = files.filter(file => file.type === 'image/png');
            // console.log(coverFile);

            const bookFile = files.filter(file => file.type === 'application/pdf');
            // console.log(bookFile);

            const formData = new FormData();
            formData.append("pdf",bookFile);
            formData.append('bigCover', coverFile);
            // console.log(formData);
           requestHandler(type, resource, {
                formData
                })
        } 
    }

    return requestHandler(type, resource, params);
};

export default addUploadCapabilities;
