Facing issue on learning portal

On the learning portal, I am gettingan error after the application introduction part

I have made all the sections live from the studio; earlier it was showing, today it started throughing error.

I tried to debug the issue, got this error, how to solve it

Hi @Diksha
what version of Tutor are you running? you can run tutor --version to confirm
Have all the course components been published in Studio? And have you tried to reindex the course in Studio?
It may be worth tailing the logs and then reproducing the error to see if the logs show anything interesting: tutor local logs -f --tail 1
you can use the </> (preformatted text) block to paste the text instead of a screenshot, as this makes it easier to read/search

Hi,

Is the course hidden?

This error is similar to the one that occurs when you hide the course in the catalog. You can check it in Studio’s advanced options.
