userPassoword not working

[muhammad707]

I have some pdf files that has passwords. I am using this library and passing password as a 'userPassword' but anyway authentication is failing.

      extract( filePath, pdftotextOptions, function( error, pages ) {
      var fullText;
      if ( error ) {
        error = new Error( 'Error extracting PDF text for file at [[ ' +
          path.basename( filePath ) + ' ]], error: ' + error.message );
        cb( error, null );
        return;
      }
      fullText = pages.join( ' ' ).trim();
      cb( null, fullText );
    });

pdftotextOptions = { 'userPassword': <some_password> }. I tried with ownerPassword too.
What I am getting is
`Error: Error extracting PDF text for file at [[ pdf-example-password.original.pdf ]], error: pdf-text-extract command failed: Command Line Error: Incorrect password
