no decode delegate for this image format `'

Question

I get strange error when I use gm package. I work with Windows x86. Already I installed gm, also imagemagick.

This is my code:

function convert(response, next) {
            console.time("convertImage");
            console.log("Reponse content type : " + response.ContentType);
            console.log("Conversion");

            GM(response.Body, fullName).setFormat('jpeg').antialias(true).density(300).toBuffer(
                function(err, buffer) {
                    if (err) {
                        next(err);
                    } else {
                        console.timeEnd("convertImage");
                        next(null, buffer);
                    }
                });
        }

This is error that I get:

Debug: internal, implementation, error
    Error: Command failed: identify.exe: no decode delegate for this image forma
t `' @ error/constitute.c/ReadImage/501.

You can see that imagemagick has jpeg support due to I can't understand what is my problem.

It looks like you are trying to run `convert` but are in fact running `identify`, so something has gone horribly wrong - maybe incompatible DLLs or versions. I think you'll need to reinstall. — Mark Setchell, Apr 22 '16 at 08:00
What reinstall? I reinstalled ImageMagick and all npms twice, but it's not working... — Rougher, Apr 22 '16 at 13:04
fullName - bucket.key (simple string), response.Body - binary of image. But already doesn't matter, I used 'sharp' npm. Thank you. — Rougher, Apr 25 '16 at 04:52
