@cortinico

because partContentType != nil alwasy true, so file content-type will never use a custom value

fox example

const form = new FormData();
form.append('raw', {
    uri: file,
    type: 'text/plain',
    name: 'raw',
});

fetch(url, {
  method:"POST",
   body: form
})

post file type never use custom value

I don't know what else to provide, it's the obvious bug

[malacca]

Add some information, react-native-cameraroll set MIMEType:nil never take effect

[cortinico]

need to change to

 if (![partContentType isEqual:[NSNull null]]) {
