geting Error on pdffiller : spawn pdftk ENOENT

I use pdffiller on my project

npm install pdffiller

and this is my code

return new Promise((resolve, reject) => {
          pdfFiller.fillFormWithFlatten(sourcePDF,distPath,formValues,false,function (err) {
              if (err) {
                return reject(err);
              }
              return resolve({
                url: distPath
              });
            }
          );
        });

and my pdf is editable and has checkboxes, input boxes and etc.

that pdf saved on sourcePDF directory

pdf filled with formValues object

every time I try to fill the pdf got this error
