Ionic Native Document video and open it in iOS

I am having this difficulty attempting to document a video with Ionic Capacitor in iOS…

the code may be very easy..

this.mediaCapture.captureVideo({period: 10, high quality: 0}).then(
    (information: MediaFile[]) =>{
      if (information.size > 0) {
        let videopath = Capacitor.convertFileSrc(information[0].fullPath);
        let video = (doc.getElementById('myvideo') as HTMLVideoElement).src = videopath;
        
        const contents = Filesystem.readFile({
          path: videopath
        })
        .then(consequence =>{
          let alert = this.alerts.create({
            buttons: ['ok'],
            message: "file exists" + JSON.stringify(consequence)
          });
          alert.then(set => set.current());
        })
        .catch(err =>{
          let alert = this.alerts.create({
            buttons: ['ok'],
            message: "error file: " + JSON.stringify(err)
          });
          alert.then(set => set.current());
        })
      }
    }  

the error is:

2022-03-13 16:47:53.446758-0500 App[3048:612360] NSURLConnection completed with error - code -1002
