Requested texture size [0x0] is invalid. on tfjs face-detection

I got this error when implemented face detection on video stream. I’v use webgl as a backend on tfjs

Uncaught (in promise) Error: Requested texture size [0x0] is invalid.

The listener

    // console.log('detector started')
    if (this.detectorInterval === null) {
      this.detectorInterval = setInterval(async () => {
        await this.detect(video, canvas, onFaceDetected, onMultiFaceDetected);
      }, 100);
    }

and detect function

async detect(input, canvas, onFaceDetected, onMultiFaceDetected) {
    const estimationConfig = { flipHorizontal: false };
    const faces = await this.detector.estimateFaces(input, estimationConfig);
    const ctx = canvas.getContext("2d");
    // console.log(faces)

    if (faces.length !== 0) onFaceDetected(true);
    else onFaceDetected(false);

    if (faces.length > 1) onMultiFaceDetected(true);
    else onMultiFaceDetected(false);

    requestAnimationFrame(() => drawFaces(faces, ctx));
  }

The input(video) param is always have hight and weight but got that error Error: Requested texture size [0x0] is invalid. how to resolve the error? Thanks for your help :pray:
