Invalid parameter error by ImageMagick instead of gm

[spursy]

When I use ImageMagick by ImageMagick instead of gm, I encounter the the followed issues.

My machine environment is windows, I have insatll imagemagick.exe in my PC.
My node is V8.5.0

{ Error: Command failed: Invalid Parameter - D:\picScrop\myapp\public\images

    at ChildProcess.onExit (D:\picScrop\myapp\node_modules\gm\lib\command.js:301
:17)
    at emitTwo (events.js:125:13)
    at ChildProcess.emit (events.js:213:7)

    at Pipe._handle.close [as _onclose] (net.js:545:12) code: 4, signal: null }

The followed is my code

     var gm = require('gm').subClass({imageMagick: true});

    const imagePath = path.join(__dirname, '../views/pic/sago.jpg');
    const resultPath = path.join(__dirname, '../public/images');
    gm(imagePath)
       /* .resize()
        .autoOrient()*/
        .write(resultPath, function(err, result) {
            if (err) {
                console.log(err);
                res.send('2' + err);
            } else {
                console.log(JSON.stringify(result));
                res.send('123'+ result);
            }
        });
