shiny's 'execution halted' message

[road2you]

I can't execute the Hello, Shiny example.
The error message is as below.

Error in !is.na(preserve) || isTRUE(format$render$`code-link`) : 
  'length = 2' in coercion to 'logical(1)'
Calls: .main -> execute
Execution halted

The separated version that creates a server.R file separately works like a charm.

Following is my session info :

I did not make any modifications to the simple example code.

All three shiny examples(Old Faithful, K-Means, Diamonds) can't be executed.

For Old Faithful and K-Means, rendering works by creating a separate server.R file.
For Diamonds, by separating server.R file AND removing the chunk argument of #| context: setup (and add library(ggplot2) to server.R) rendering works.

I think it may be that the chunk argument related to shiny is not properly handled.

I am seeing a warning rather than an error (perhaps in your config warnings are treated as errors?)

In any case, I have fixed the code to eliminate the warning here (b7878d2) so this should no longer be an issue.

After installing quarto version 0.9.476, the rendering proceeds to the end and succeeds. No error message appears. Thank you.
