h5p file not found

Hello, I need you to guide me because I have not been able to solve the issue, I have investigated in documents and not found the answer, I am working on localhost, to present content, I have all the h5p plugins that I found installed in moodle, and when I do the activity and I try to call it to show it, I get this error, can someone tell me what happens? I would like to generate content without using the iframe of h5p.org but something more native to the platform, is there any way or it depends on the server and iframes external, thank you!

Moodle 3.9.6+

error in Timeline


I think there is a problem in timeline, i tried on the Moodle I use and here, I think is a coding problem.

If I try to use "eras", the headline shows correctly, but "Text Era body" seems to be perfectly useless: the text I put in the form doesn't show anywere... If you look at the images, I put a text but it doesn't appears in the timeline.
