Bug with Shiny Server v1.5.21.1145

[sebsilas]

This probably is unlikely to affect anyone, since the version of Shiny Server in question is now out-of-date, but just to document in case someone else experiences this:

Shiny Server v1.5.21.1145 caused a weird psychTestR bug, whereby running a psychTestR (but not normal Shiny) app caused URLs to be structured as if they have a directory e.g.,

https://website.com/my-psychtestr-app/_w_c964a2a0f0257615b33ae0106e727dbe1d66395770430b18/?language=en&p_id=participantid

whereas normally, you would expect:

https://website.com/my-psychtestr-app/?language=en&p_id=participantid

This led to other issues. For example, in the JAJ test, when clicking on a dot, the click made the app think the user wanted to move a directory out (../) and thus asked the user if they wanted to quit the app.

Solution: upgrade to v1.5.22.1017

I'm guessing this was a Shiny Server issue that got resolved in 1.5.22.
