How proxing the upload files to request.js to another server without saving locally

[anarkiVan]

Hello! I have the problem need help plz.
I have apollo-server-express 2.9 and the client send file there. Me need proxing this request to the other server.
BUT! i cann't do this and i have error GraphQLError: Error: socket hang up:(
EXAMPLE:

async mutationResolver( _, { contacts : { user_scans, ...otherData } }, ctx ) {
  const getFileData = async ( filePromise ) => {
    const { filename, mimetype, createReadStream } = await filePromise;
    const stream = createReadStream();
    await new Promise( ( res, rej ) => {
      stream
      .on( 'error', error => {
        console.error('There was an error.');
        reject( error );
      } )
      .on( 'end', () => {
        res();
      } )
      .resume();
    } );

    return {
      value   : stream,
        options : {
          filename,
          contentType : mimetype,
        },
     };
  };
  // user_scans are promise files array from client
  const fileDataPromises = user_scans.map( getFileData );
  const files = await Promise.all( filedDataPromises );
  // swagger 2.0 does not understand file array and this hack need
  const attachFiles = files.reduce( ( acc, file, index ) => {
    return {
      ...acc,
      [`user_scan_${index + 1}`] : file,
    };
  }, {} );

  const formData = {
    ...otherData,
    ...attachFiles,
  };
  // customRp is request-promise with deafult headers
  const response = await customRp( {
    uri    : myOtherServerURL,
    method : 'POST',
    formData,
  } );
}

And i have error GraphQLError: Error: socket hang up. But if i send files with fs.createReadStream('./file1.jpg') it WORKS!(

I'm sorry, but this looks like a usage question that might be better suited for Stack Overflow or another discussion forum.

without saving locally

As a tip, you will not be able to avoid the temp file being created via fs-capacitor, you can read about the architecture here.

Your code is a little confusing to me, so I won't comment on your situation exactly but you should be able to figure out how to stream files out to another server; that is how most of us are processing file uploads. I stream my files up to DigitalOcean Spaces.

Of course, if you find a specific bug with minimal reproduction steps we can reopen.

thank you! i found explain in this issue form-data/form-data#394
trouble was be with compatibility between stream from fs-capacitor and form-data which used to request.js underhood as I understand
