Out of the blue I started getting a "R Session Disconnected" message when opening the RStudio and even pressing the botton for Reconnect the following is a "R Session Aborted" error message followed by a new initiation of RStudio which enters in this loop of Session Disconnected.
In that first message, there is some indicative that "this browser was disconnected from the R because another browser connected". I did not make any change in my enviroment to justify such error. Already desinstalled and installed R and RStudio and those errors continue.
I´m using OneDrive to store some files, I don´t know if this may be associated with the problem but even in OneDrive I did not change anything that could be associated with.

I'm using gmailr in an automatic R script to send out some emails. It's been working fine for about a month and a half, but recently it failed with the following error:
Error: Can't get Google credentials.
Are you running gmailr in a non-interactive session? Consider:
* Call `gm_auth()` directly with all necessary specifics.
Execution halted
My code, which hasn't changed, is
library(gmailr)
options(gargle_oauth_email = TRUE)
gm_auth_configure(path ="data/credentials.json")
gm_auth(email = TRUE, cache = ".secret")
and is run non-interactively. (there is only one token in the .secrets folder) When I now ran it interactively, it "did the dance" and opened up the authentication thingy in the browser, which I confirmed and now everything is running fine again.
The problem is that I don't understand why the credentials suddenly required re-authentication or how I could prevent the script failing like this in the future.
You can try to clean cache in gargle folder and then create new one.
It worked for me, when i had similar problem
gm_auth function with gargle_oauth_cache stop working
I am running a few scheduled jobs on RStudio Server I host on my home computer.
It seems like there is no straightforward way to set an email warning when something goes bust.
I am using package cronR for scheduling jobs and emayili for sending emails.
I can see that it is possible from within Linux, but I have it all already set up in R..
Any way I can combine these two and make this work from within R?
I am working in a Shiny app that connects to Comscore using their API. Any attempt at executing POST commands inside future/promises fails with the cryptic error:
Warning: Error in curl::curl_fetch_memory: Bulk data encryption algorithm failed in selected cipher suite.
This happens with any POST attempt, not only when/if I try to call Comscore´s servers. As an example of a simple, harmless and uncomplicated POST request that fails, here is one:
rubbish <- future(POST('https://appsilon.com/an-example-of-how-to-use-the-new-r-promises-package/'))
print(value(rubbish))
But everything works fine if I don not use futures/promises.
The problem I want to solve is that currently we have an app that works fine in a single user environment, but it must be upgraded for a multiuser scenario to be served by a dedicated Shiny Server machine. The app makes several such calls in a row (from a few dozen to some hundreds), taking from 5 to 15 minutes.
The code is running inside an observeEvent block, triggered by a button clicked by the user when he has configured the request to be submitted.
My actual code is longer, and there are other lines both before and after the POST command in order to prepare the request and then process the received answer.
I have verified that all lines before the POST command get executed, so the problem seems to be there, in the attempt to do a POST connecting to the outside world from inside a promise.
I am using RStudio Server 1.1.453 along with R 3.5.0 in a RHEL server.
Package versions are
shiny: 1.1.0
httr: 1.3.1
future; 1.9.0
promise: 1.0.1
Thanks in advance,
Every now and then I have to run a function that takes a lot of time and I need to interrupt the processing before it's complete. To do so, I click on the red sign of "stop" at the top of the console in Rstudio, which quite often returns this message below:
R is not responding to your request to interrupt processing so to stop the current operation you may need to terminate R entirely.
Terminating R will cause your R session to immediately abort. Active computations will be interrupted and unsaved source file changes and workspace objects will be discarded.
Do you want to terminate R now?
The problem is that I click "No" and then Rstudios seems to freeze completely. I would like to know if others face a similar issue and if there is any way to get around this.
Is there a way to stop a process in Rstudio quickly without loosing the objects in the workspace?
Unfortunately, RStudio is currently not able to interrupt R in a couple situations:
R is executing an external program (e.g. you cannot interrupt system("sleep 10")),
R is executing (for example) a C / C++ library call that doesn't provide R an opportunity to check for interrupts.
In such a case, the only option is to forcefully kill the R process -- hopefully this is something that could change in a future iteration of RStudio.
EDIT: RStudio v1.2 should now better handle interrupts in many of these contexts.
This could happen when R is not working within R and is invoking an external library call. The only option is to close the project window. Fortunately, unsaved changes including objects are retained on opening RStudio again.
I am currently trying to get search working in my Tridion 2011 installation. I read in another article that I should run the TcmReIndex.exe tool in the Tridion/bin folder to re-index all my sites. So I tried this and it failed with a message box giving the following details
Unable to get list of Publication items.
Unable to Intialize TDSE object.
The wait operation timed out
Connection Timeout Expired. The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement. This could be because the pre-login handshake failed or the server was unable to respond back in time. The duration spent while attempting to connect to this server was - [Pre-Login] initialization=21054; handshake=35;
The wait operation timed out
A database error occurred while executing Stored Procedure "EDA_TRUSTEES_GETTRUSTEEETOKEN"
I have four fairly large publications (100 000+ items in total) which I am trying to index.
Any ideas?
Whenever I get "Unable to Intialize TDSE object." errors, I typically write a small test script using VBScript, and try running it on the CMS server. Whilst this does not directly solve the problem, it often gives some insight into the issue by logging information in the event viewer. Try creating a test.vbs file as follows and running it:
Set tdse = CreateObject("TDS.TDSE")
tdse.initialize()
msgbox(tdse.User.Description)
Set tdse = Nothing
If it throws any errors, please let me know, and it may help us solve the problem. If it gives you a popup with your user description, then I am completely barking up the wrong tree.
I haven't come to anything conclusive but it seems like my issue may have been a temporary one as it just started working. I did increase all timeouts in Tridion MMC > Timeout Settings by 100 times their amounts but I suspect that this wasn't the issue, when it works the connection is almost instant.
If anyone else has this issue
Restart the computer the content manager is installed on, try again.
Wait an hour or two, try again.
Increase timeouts, try again.
I've run the process a few more times and it seems to be working correctly.
