In the 8.x-1.5 release we removed the (manually written) composer.json file from the project repository, allowing drupal.org to generate it automatically.
Maybe in your project you upgraded from an older release and that file stuck around for some reason. Can you try to delete the module's directory and then execute a composer install to bring it back, and see if that solves your issues?
