Error in database when trying to download any activity

We have a Moodle platform in version 3.1.1 (Build: 20160711). The 2017031300 version of the H5P plugin has been installed. It is a very powerful plugin to which you can draw a lot of performance to the activities within the courses of the platform. We have detected an error that occurs over any type of content that has been created. The problem is when you want to download that activity created in the Moodle platform to take it to other courses, it gives the following error in Moodle debug mode:

Debug info: ERROR: invalid input syntax for integer: "4.h5p"

I attached screen shots so that they know exactly where the error occurs.

Thank you very much first of all and congratulations for this wonderful module.

Thank you for the detailed bug report, the issue was resolved in: and should be included in the next Moodle release.

Thank you very much for the quick answer.

I was looking at the code to change it and exactly it was these lines that I modified so that it worked before you sent me the answer.

Now I check that the activity is downloaded well, but for other activities, the action of "Download" does nothing. I do not download the activity nor give me an error. It is as if for that activity the "Download" action does nothing.

Is it possible to download any type of activity, or are there activities for which you can not download in h5p file? I did the test with the conference room and the memory game.

It should be possible to download any H5Ps as long as the "download" button is showing. Could you check your console and your server error log for any errors when no download file is produced ?

Solved!!! Great job!!! ;)
