TypeError: Cannot read property 'insertSlide' of null (line 60, file "Code")

Question

Would be grateful for any guidance on how to fix this error. Please see below code which gives the error,

  // Copy a slide from another presentation and inserts it.
  var otherPresentation = SlidesApp.openById('1Fz6YWCyLIdHfDoonz-40qRlmnNCWwROIQjXqYwmRxS8');
  var currentPresentation = SlidesApp.getActivePresentation();
  var slide_v1 = otherPresentation.getSlides[0];
  var insertionIndex = 1;
  currentPresentation.insertSlide(insertionIndex, slide_v1);

Thanks to Tanaike and some changes to the code - this has been solved. Please see updated code below.

  // Copy a slide from another presentation and inserts it.
  var otherPresentation = SlidesApp.openById('1Fz6YWCyLIdHfDoonz-40qRlmnNCWwROIQjXqYwmRxS8');
  var currentPresentation = SlidesApp.openById(documentId);
  var slide_v1 = otherPresentation.getSlides()[0];
  var insertionIndex = 1;
  currentPresentation.insertSlide(insertionIndex, slide_v1);

Using [0] has definitely helped after the getSlides()

I have removed .duplicate() because it creates duplicates on the template.
