I know I'm not the only one with this problem but I have tried several solutions and nothing has worked yet. When I'm deploying my shinyapp (that works perfectly on Windows 11 and 10) i get this warning:
Warning messages:
1: In fileDependencies.R(file) :
Failed to parse C:/Users/nicol/AppData/Local/Temp/RtmpQF8uhX/file438c489067a3/app.R ; dependencies in this file will not be discovered.
I have tried saving my app as a UTF-8 file (there are German Umlauts in it) in RStudio and I have tried to use this as the first line of my code:
options(encoding = "UTF-8")
I deploy on the Rstuido GUI. Maybe that's the problem. But I don't understand how to deploy through the commandline.
Thx for your help
Found a solution. You have to deploy your app through the commandline and use this:
tmp.enc <- options()$encoding
options(encoding = "UTF-8")
rsconnect:: deployApp()
This can be a bit complicated because you can't chose from the GUI what you want to upload to shinymaps.io but at least it works.

I wanted to make internally sharing/locally launching a shiny app developed with the {golem} framework a little more robust.
Hence, I used the renv package and installed the shiny app as a local package into a project folder.
I proceeded as follows (thanks #Kat for the suggestion):
initialize renv using renv::init(bare = TRUE)
renv::install("my_local_package")
renv::snapshot(type = "all")
renv::isolate()
Writing a launch file consisting of:
library(golempackage)
renv::restore()
golempackage::run_app(options = list(launch.browser = TRUE))
Share folder.
However, when launching the shiny app on a different computer (or a docker testing environment), I get the following error caused by the package bslib. Same happens when I delete my cache:
An error has occurred!
File attachments must exist: 'C:/Users/XYZ/AppData/Local/R/cache/R/renv/cache/v5/.../bslib/lib/bs3/assets/fonts'
Note: this error even occurs if I set the cache to be project-local and share it inside the project folder.
However, now the error message does not reference the global but the project-local cache. Unfortunately still as an absolute path which throws an error for other users.
This is all super weird and I have not the slightest idea why this occurs.
I would like to avoid removing bslib.
As far as I can see, the error is coming from the sass package, e.g.
https://github.com/rstudio/sass/blob/f7a954027447dd0b9826ec01c7084c89a6e64fcc/R/layers.R#L442-L443
While I don't know exactly know what's going on, you could probably use the R debugger to check why that's failing. (Does the referenced folder exist in both cases? Are you expecting renv to be using the cache in the second case?)
I created an Rshiny APP on my Mac and tried to upload to shinyapps.io
However, when I press 'Publish' button at the top right corner, it shows an error.
Preparing to deploy application...DONE
Uploading bundle for application: 609021...Error in inferAppPrimaryDoc(appPrimaryDoc = appPrimaryDoc, appFiles = appFiles, :
Application mode static requires at least one document.
Calls: <Anonymous> ... withStatus -> force -> bundleApp -> inferAppPrimaryDoc
Execution halted
This problem has been solved. See the first answer.
But now, I have another problem.
I can publish it, but the app cannot show the graphs.
I check the log and it says,
Warning: Error in : Aesthetics must be either length 1 or the same as the data (1): x, y, label, vjust, fill
Also, there is another warning,
Warning in Ops.factor(Year, start) : ‘>=’ not meaningful for factors.
It is pretty strange because when I run the app on my own laptop, it works super well. Please help...
Thanks,
Weichen
You don't have to split your code to ui.R and server.R.
Here is how I solved it on Rstudio:
I created a new Shiny app.R file.
This creates a new folder inside the working directory. I copied all data files I use inside my app into that folder.
I copied and pasted my whole code into the new app.R file on Rstudio.
I clicked Publish and I chose all the data files I use together with the app.R for upload.
It worked. I am not sure why it wasn't working before even though I was still choosing the right files together; I guess because they weren't in the right folder for the Shiny app.
edit: don't forget to Save the app.R file before publishing
Solved.
At first, I simply execute the shiny.R (the whole code) Wrong!
Try this. Create two r files under the same directory.
ui.R
server.R
and then executive shiny.R
You would see an amazing thing happen.
Solved the second problem.
Change the type of 'Year' to numeric by as.numeric
However, I still cannot understand because I can run app on my own laptop.
BTW, the logs in shinyapps.io help me target the problem.
I am currently moving a (localhost) shiny App from a windows 32-bit to windows 64-bit . Google didn't managed to answer my problem :( so I'm asking the community !
This App worked fine on 32 bits, I had to re-install R, all Packages, Java on the 64-bit machine (each in the 64-bit mode). My app has the following file architecture :
a gloabl.R file where I load libraries
a server.R
List item
a ui.R
another file which format data to be sent d3/nvd3
a JS file to display a linechart.
the error I have is the following :
Warning in file(con, "rb") : file("") only supports open = "w+" and
open = "w+b": using the former Warning: Error in readChar: invalid
'nchars' argument Stack trace (innermost first):
1: runApp Error : invalid 'nchars' argument
When I'm running code without shiny, all works fine, all is precessed and results are good.
Does anyone has ever been facing to this ?
If you need anything just ask I will be more specific. I am not giving you the code, he is a little tricky and is in multiple files... And I think it is specific to my new environement.
Reinstalling solely the shiny-package fixed the problem for me. I am using R-studio, and did the operation through the Packages window (deleted and reinstalled).
I'm trying for the first time to deploy an App on ShinyApp.io and I manage some issues do it.
I ran the command :
>shinyapps::deployApp('C:/Users/Karim/Documents/test')
And the following message appeared :
Preparing to deploy application...DONE
Uploading bundle for application: 66633...
Error in digest::digest(file.path(appDir, file), algo = "md5", file = TRUE) :
The file does not exist: C:\WINDOWS\TEMP\RtmpugxfSW\fileabc59e7164e/..
I noted that the file mentioned (C:\Windows\Temp...) does exist and contains ui and server files. Yet I don't know which file is missing.
I tried to see if there was no similar cases in the forum by I didn't find similar mistakes.
If anyone know how to solve this error or guide me.
Thank you in advance.
Karim.
Try using relative rather than absolute paths,

Hi I'm having a million problems trying to publish my app to shiny.io.
Firstly, I have Rtools 3.2 installed in my computer and set to the Path, but it is not recognized in the registry. Nevermind, this code should fix it:
install.packages("installr")
library(installr)
install.Rtools(choose_version = FALSE, check = TRUE, use_GUI = TRUE,
page_with_download_url = "http://cran.r-project.org/bin/windows/Rtools/, keep_install_file=TRUE")
install.packages("devtools")
library(devtools)
devtools::install_github('rstudio/shinyapps')
Next, to deploy my app to my shiny.io account:
library(shinyapps)
shinyapps::setAccountInfo(name='xxxx', token='xxxxxxxxxx', secret='xxxxxxxx')
Then my app starts running in a browser, and I click publish to my shiny account. However, when the app is being deployed, it shows the following error:
Preparing to deploy application...Error: /v1/applications/ 400 - Validation Error
Execution halted
Any ideas what the problems may be? Thank you.
I had the same error returned. In my case the problem was the name of the app itself. Deployed apps must have names at least 4 characters long with no spaces.
Setting an application name solved this problem for me. My application directory contained a space.
deployApp(appName = "myapp")
I had the same problem, however, my app name was fine and even adding 'appName =' did not help. Just a side note that this issue came up because I changed the name of my folder in effort to change the name of my app in shinyapp.io
The only thing that worked for me is publishing through the "Publish" button of Rstudio on upper right. I would recommend publishing using that instead of command. You can select files you do not want to publish within the App folder and you can publish the app under a different name then your local name.
I also had similar errors and the issue was resolved after I changed the name of the directory that holds the "app.R" file from only 3 characters to more than 4 characters.
