Issues with thematic after shiny update - plots not displayed, error with shiny::getCurrentOutputInfo()

Hello,

Since I updated shiny to the newest version (1.6) I'm having issues with the thematic package in shiny.
My plots no longer display and I see this error message:
"Error in FUN(X[[i]], ...) :
Expected shiny::getCurrentOutputInfo() to return reactive expressions. Try upgrading shiny: install.packages('shiny')
Warning: Error in FUN: Expected shiny::getCurrentOutputInfo() to return reactive expressions. Try upgrading shiny: install.packages('shiny')

125: drawPlot

95: drawReactive
82: renderFunc

I have since updated all the packages and R and nothing seems to fix this problem... It's not to do with my code, because I also tried just copy-pasting code from examples online and the error still appears. The only fix is to not use thematic::thematic_shiny(), but this way my plots are not customized to the theme I set for my app.

Any idea what might be going on? Any help will be appreciated.

What version of thematic do you have? Have you installed it from CRAN install.packages('thematic')? If you're still having problems, please include the output of sessioninfo::session_info()

Hmm, ok, have you tried restarting the R session and re-running the app?

It worked!

Thank you very much for your help.
