Shiny file.path error

mostlyrobots · June 17, 2020, 5:58pm

I've run into a problem with a fresh shiny install. Launching an app opens a browser window and returns an error from file.path. No information is in the logs and there is no traceback to show what caller is causing the problem.

library(shiny)
runExample('01_hello')

Listening on http://127.0.0.1:7009
Warning: Error in file.path: cannot coerce type 'closure' to vector of type 'character'
[No stack trace available]

The server is a RHEL 8.2 box with Shiny 1.4.0.2 and the error appears with both R 4.0.1 and R 3.6.3.

My guess is that something on the system is misconfigured but I can't figure out what with so little information returned.

Any thoughts?

Follow up to https://github.com/rstudio/htmltools/pull/159 (the new `path` tag i…s overriding the `path` argument to `tabContentHelper()`) ```r > options(shiny.fullstacktrace = T) > shiny::runExample("001_hello") Listening on http://127.0.0.1:5684 Warning: Error in file.path: cannot coerce type 'closure' to vector of type 'character' 97: h 96: .handleSimpleError 95: file.path 94: find.file.ci 93: file.path.ci 92: base::file 91: readUTF8 90: paste 89: dots_list 88: tags$code 87: format 86: HTML 85: dots_list 84: pre 83: dots_list 82: div 81: eval 80: eval 79: with.default ```

Perhaps until fixes are merged avoid showcase mode?
