Hope the testing confirmed that error.
As Moodle 3.8 will be released next week, just upgraded a MoodleBox- "Upgrading Moodle database from version 3.7.1+ (Build: 20190824) (2019052001.09) to 3.8rc1 (Build: 20191115) (2019111500.00)".
3.8rc1 did not come with the integrated, (in 3.8 ), h5p plugin ; h5p plugin installed without any issues on the upgraded MoodleBox.
Welcome to the world of H5P!
To get started with H5P and Moodle take a look at our tutorial and check out the example content at H5P.org for inspiration.
We hope you will enjoy H5P and get engaged in our growing community through our forums.
If you have any feedback, don't hesitate to contact us. We take feedback very seriously and are dedicated to making H5P better every day!
H5P fetches content types directly from the H5P Hub. In order to do this the H5P plugin will communicate with the Hub once a day to fetch information about new and updated content types. It will send in anonymous data to the Hub about H5P usage. Read more at the plugin communication page at H5P.org.
