a and b will cause error [Error: ReactNativeBlobUtil.fetchBlobForm failed to create request body]

c will not throw this exception but seems like tries to pass empty file

i picked file by react-native-document-picker, then uploaded to server. My file like this: { "fileCopyUri": "file:///var/mobile/Containers/Data/Application/.../PNG%20image.png", "name": "PNG image.png", "size": 2124954, "type": "image/png", "uri": "file:///private/var/mobile/Containers/Data/Application/.../PNG%20image.png" } and i resolved:

await ReactNativeBlobUtil.fetch( 'POST', url, { 'Content-Type': 'multipart/form-data', }, [ { name: 'FileData', filename: file.name, data: ReactNativeBlobUtil.wrap( Platform.OS === 'ios' ? decodeURIComponent(file.uri.replace('file://', '')) : file.uri, ), }, ......... i hope it can help u.
