Problem receiving data in a promise

  • 772

I ask this question because I have a problem when receiving some data in a promise.

return res.status(200).send({message: 'Se ha subido el archivo de video satisfactoriamente.', video: updatedVideo, file_name: file_name});

That's what the video controller returns, made in NodeJs.

        (result) => {
            console.log(result);
            this.video.setFile(result.file_name);
            alert('Se ha actualizado el video del registro.');
        },

and this is the part of TypeScript where I get the name of the file. But when I go to run the application it gives me this error:

error TS2339: Property 'file_name' does not exist on type '{}'.

The fact is that once I have managed to execute it by commenting out the sentences that caused the error, and making it appear in the "result" console, I perfectly receive file_name, etc. Can someone give me a hand to receive that: "file_name" correctly? Thanks in advance.

    I managed to access the value I needed like this:

    (result) => {
        console.log(result);
        this.video.image = result['file_name'];
        alert('Se ha actualizado la imagen del registro.');
},

    Thank you very much aldanux for your attention.
