Hi, I just had the same issue and thought I should share my solution here: You have to make sure, that your html structure is correct. It must have the following elements:

• ngbAccordion
  • ngbAccordionItem
    • ngbAccordionHeader
      • ngbAccordionButton
    • ngbAccordionCollapse
      • ngbAccordionBody
        • ng-template

In my case, I misspelled ngbAccordionCollapse.
