Updating Drupal 8 module fails

Hi,

I'm trying to update the module from 8.x-1.0-rc16 to rc17 using the command composer require 'drupal/h5p:^1.0-rc17'

However I'm getting issues:

  Problem 1

    - Can only install one of: h5p/h5p-editor[1.24.1, 1.23.1].

    - Can only install one of: h5p/h5p-editor[1.24.1, 1.23.1].

    - Can only install one of: h5p/h5p-editor[1.24.1, 1.23.1].

    - drupal/h5p 1.0.0-rc17 requires h5p/h5p-editor 1.24.1 -> satisfiable by h5p/h5p-editor[1.24.1].

    - Installation request for drupal/h5p ^1.0-rc17 -> satisfiable by drupal/h5p[1.0.0-rc17].

    - Installation request for h5p/h5p-editor (locked at 1.23.1) -> satisfiable by h5p/h5p-editor[1.23.1].

I'm not entirely sure how to fix these. Any help would be appreciated.

Thanks,

Bez
