Strange behavior where Interactive Apps will disappear from that menu and it’s specific to a user. Seems to be server side as a fresh browser session won’t resolve it. But, killing off and creating a new PUN for the user doesn’t solve it as well. This is on v3.0.

Typically for something only one user is experiencing you should take a look at the `bashrc` file to see if there’s anything to their environment which would break OOD.

Also, check the logs which you can read about in the docs here:

> **[/var/log/httpd/\<hostname\>\_error.log - Logging — Open OnDemand 4.2.0...](https://osc.github.io/ood-documentation/latest/how-tos/monitoring/logging.html#system-logs)**
>
> This page provides an overview of the locations Open OnDemand writes logs and useful session data and provides context around these locations.

The NGINX logs for the user might be your best guide here since it’s particular to them.

It was a yaml formatting error in the app `form.yml.erb` which had dynamic elements pulled from a user’s environment or files.

What was difficult to debug was that the app just disappears from the menu and can’t be accessed to see any error message. There was also no errors in the NGINX logs. Only by going to the URL of the app itself did we see `Psych::SyntaxError: (): did not find expected node content while parsing a flow node at line 84 column 16` which clued us on to a yaml syntax error arising after creating ERB-defined yaml elements.
