Ionic-native/image-picker not works ((

Good day! I make a multi-selection of images from the gallery in the application. I use @ionic-native/image-picker@4. When you select one image everything works fine but if you select two or more images the app crush. Help please.

This is my code:

  fromGallery() {

    let options: ImagePickerOptions = {  
      quality: 100,  
      width: 600,  
      height: 600,  
      outputType: 1,
      maximumImagesCount: 15
  };  
  this.imagePicker.getPictures(options).then((results) => { 
    console.log('Results', results);   
      for (let index = 0; index < results.length; index++) {  
          this.imgs.push('data:image/jpeg;base64,' + results[index]);  
      }  
      console.log('Image Lists', this.imgs);  
  }, (error) => {  
      console.log('Error occurred while loading', error);  
  });

  }
