Problem/Motivation

On a D8 Opigno install, the Fill in the Blank answer type will not display. It can be edited normally, but when loading for an end user, we get the following error:

Uncaught TypeError: can't access property "prototype", Question is undefined

Steps to reproduce

  • Install Opingo
  • Add a Fill in the Blank activity
  • Add activity to a module
  • Try to load the activity

The activity never loads, and the Loading spinner never stops.

The error seems similar to the one for a different H5P component: https://www.drupal.org/project/h5p/issues/3169008 →

The remedy there to turn off JS aggregation did not help here.

    Suggest closing: Fill in the blanks works in D11 with H5P module alpha6. Issue is 4 years old. Not clear if Opigno is relevant.

    I may need more info to help with debugging. As far as I understand it, Opigno manages the version and installation of this module as well as the h5p libraries. If the activity type works ok in this module without Opigno my instinct is to direct support requests to the Opigno module directly. If anyone has more info on how this module needs to adapt to support Opigno that is useful too!
