Unable to author content: H5P, Drupal 8, Docker

Colin D's picture

I am trying to get H5P and Drupal 8 running in a dockerised environment. I have installed H5P and several of the libraries but during the content authoring process I press the 'save' button to submit the form and I get a white screen of death with an 'unexpected error' mesage. It appears as though the ajax callback is not working. When I check my server logs I get error messages such as the following. Does anyone have any ideas how I might solve this issue so I can author content?
