Use Playlists to create collections of video or audio files in Microsoft 365

Another limitation/bug is that it is impossible to change the column formatting in any way. Even changing the letter "e" in one example of "elmType" to the letter "e" results in the list showing the error: "Something went wrong undefined is not valid JSON". The simplest changes result in this error. Another example, cut all or part of the text in the column formatting box and paste it back unchanged and this error will be the result. If the list is completely empty the error does not appear but as soon as one of more videos are added, the error is shown. So it is not possible to change anything in this templates list formatting. It actually breaks sharepoint as the gear icon at the top of the page will only show "Sharepoint loading" and not any of the normal options like "List settings".

I have tried doing similar things with other Microsoft templates such as "Issue Tracker" and unsurprisingly changing a "{" to "{" or "e" to "e" doesn't break the template. How the Playlist template knows that the letter "e" has been changed to the letter "e" and therefore should not work is a mystery and why anyone at Microsoft should  think this is a necessary feature is also a mystery but there we are.
