r - shiny The application unexpectedly exited -


i made shiny application on local machine working. face pop-up error message "the application unexpectedly exited. diagnostic information has been dumped javascript error console." when deployed app on server shiny-server.

i checked javascript error console. nothing special message. normal message like,

listening on http://127.0.0.1:46683 loading required package: dbi  attaching package: ‘dplyr’  following object masked ‘package:stats’:  filter following objects masked ‘package:base’:  intersect, setdiff, setequal, union

i tried edit solve problem. found 'observe()' , 'updateselectinput()' function may cause error. error pop-up appears when server.r has

observe({ vars <- input$input1 * 1:100 updateselectinput(session = hoge, inputid = "input2", choices = vars, selected = vars[1]) })

the pop-up error not appear when function not in server.r

is bug of shiny-server? if not, how can avoid pop-up error message? if have solution problem, please let me know.

my shiny 0.11.1.9005 , installed shiny-server source.

best,
