and I get come to take photo log well. but after taking picture,
it goes to catch clause saying

this is error: error Error capturing image.

      const options : CameraOptions={
        quality:50,
        targetHeight:600,
        targetWidth:600,
        destinationType:this.camera.DestinationType.DATA_URL,
        encodingType:this.camera.EncodingType.JPEG,
        mediaType:this.camera.MediaType.PICTURE,
        saveToPhotoAlbum:true
      }
      console.log("come to take photo");
      const result= this.camera.getPicture(options).then(imagedata=>{
      
        console.log("get pic");
        console.log(imagedata);
        // if(imagedata!=undefined){
        //   this.picdata=imagedata;
        //   this.upload(value);
        // }
        
      }).catch(e){
      console.log("this is error: error "+e);
    }


    }

I should have deleted saveToPhotoAlbum:true
