When I am trying to load this pdf http://merlin_test.s3.amazonaws.com/myPdf.pdf, it's unable to render all the contents. There is a blue background which is not visible and some of the texts are not visible as well as the color is not proper. Can someone please help

this.setLeading(-y);
    this.moveText(x, y);
  }
  setTextMatrix(a, b, c, d, e, f) {
    this.current.textMatrix = [a, b, c, d, e, f];
    this.current.textMatrixScale = Math.hypot(a, b);
    this.current.x = this.current.lineX = 0;
    this.current.y = this.current.lineY = 0;
  }
  nextLine() {
    this.moveText(0, this.current.leading);
  }
  paintChar(character, x, y, patternTransform, resetLineWidthToOne) {
    const ctx = this.ctx;
    const current = this.current;
    const font = current.font;
    const textRenderingMode = current.textRenderingMode;
    const fontSize = current.fontSize / current.fontSizeScale;
    const fillStrokeMode =
      textRenderingMode & TextRenderingMode.FILL_STROKE_MASK;
    const isAddToPathSet = !!(
      textRenderingMode & TextRenderingMode.ADD_TO_PATH_FLAG
    );
    const patternFill = current.patternFill && !font.missingFile;
    let addToPath;
    if (font.disableFontFace || isAddToPathSet || patternFill) {
      addToPath = font.getPathGenerator(this.commonObjs, character);
    }
