reprex:::reprex_addin() on posit cloud does not show the preview

[RaymondBalise]

I was trying to demo {reprex} to students yesterday and when I used Render reprex... from the Addins context specific menu:

and checked on Preview HTML

the reprex was rendered but there was no preview.

raw_data <- data.frame(person = "ray", mood = "confused")
data$mood
#> Error in data$mood: object of type 'closure' is not subsettable

^{Created on 2023-02-02 with reprex v2.0.2}

If I use the console, everything works as it should:

reprex::reprexO

I am teaching novices. So lightening their memory load, by only requiring them to recognize the name reprex from the menu, instead of having to recall the package name then :: and the function is highly preferable.

Help...

I can reproduce this and so far I don't have any theory on why it's happening. I'm going to ask the posit cloud team.

If I walk through the code in the debugger, the problem goes away 😬
