Oceano app: Time series error

bbest commented 1 year ago

From @evsatt:

Hey Ben and Marina, I hope you are well :) I was just showing the OPC Offshore winds person our app, as they would like to use it for looking at trends in the wind call area over time. But I can't figure out why it won't generate a time series graph. Do you have thoughts on if this is user error or if there is something with permissions going on on the backend? Thanks! Erin

Look at server log

Debug by hopping on as user bebest:

https://rstudio.calcofi.io

And checking out logs:

# change directory to Shiny logs
cd /var/log/shiny-server

# list all with time reversed
ls -latr

Ok, seems to be a problem with the plotting, perhaps data missing, per .xts: subscript out of bounds; or the library stringr not getting loaded since not finding str_replace().

Debug app

Set browser() in oceano/server.R around plot_ts just before dygraph plotting:

Trying first in RStudio with Run App button. Initially the app works in the Time series tab, but changing to a similar custom Area produces a more useful error:

- Error: could not find function "str_replace"

From @evsatt:

Weird -- its still throwing an error...

- An error has occurred. Check your logs or contact the app author for clarification.

Whoops, I forgot to update the main apps folder (vs apps_dev) that gets served at shiny.calcofi.io/oceano, which I did with the following commands in the Terminal of rstudio.calcofi.io:

# change directory to the main apps folder
cd /share/github/apps

# pull the latest from Github
git pull

# touch the file (to give newer timestamp) that tells Shiny server to reload the app in oceano/
touch oceano/restart.txt
