Adapt Learning Community: Preview of course not working CMD error message

good day all,

my Adapt Authoring tool has been functioning optimally for some time now. i did recently delete the node modules in the framework folder and run an npm install. Subsequent to that i have been having an issue with the Spoor (2.0.10) and resources (2.0.5) plugins, if i add anyone of these or both to a course i get an error in the AT saying that the preview could not be generated and that i should contact the admin...

The CMD error is as follows:

any idea what the issue is and how it can be resolved?

I'm getting this problem.
Has it been resolved??

This has been fixed in my installation now.

Whilst getting ffmpeg working, the re-installing of Node, Grunt and Adapt and making sure the versions were upto date, the errors went away and I can now install themes and plugins.

The preview also works as a result of the above.

FWIW,

When we get this kind of errors we usually do the following:

pm2 stop server ; grunt build ; pm2 start server
Change and save course theme to another then change and save course theme to original.
Change and save course menu to another then change and save course menu to original.

If none of this works, I usually end by removing the components from mongo and then reinstally them manually.

Hi Daniel,

I'm an Instructional Designer, but a newbie to any coding/troubleshooting in terminal etc. I tried the following:

Installed pm2
When I received the preview error, tried "pm2 stop server", but got a "Process server not found" error.
I also tried saving to a different them, then revert to the vanilla theme
I could not save to a different menu as I had trouble installing anything other than the boxMenu

Would you happen to have any other pointers for me please? Or, if you could provide a more detailed steps ("for dummies!") for the first bullet point in your post, that would be awesome!

I would LOVE to get Adapt to work me as it would be a perfect tool for some of our mobile/microlearning lessons. I spent hours and days troubleshooting all the installation issues and got it working, only to get stuck at this preview error for the past couple of weeks! :(

@Paul,

I tried your fix (ensuring ffmpeg was working, then re-installed node, npm, grunt, adapt authoring tool) and ensured to update them, but no luck!

Thanks in advance for your help!

Sebastin
