Problem copying token and secret into RStudio: Error in function (type, msg, asError = TRUE)

[Seth Green]

Hello,

I am fairly new to shiny and I've been using it for some projects for a class I've been taking.  It has worked great for the past several months, but this morning I tried to deploy a new App and I am having a problem.

I go to the shinyapp.io and log in to my account and copy my token and secret to the clipboard.  However, when I paste them into RStudio, I get the following error:

`

Error in function (type, msg, asError = TRUE)  : 

  error setting certificate verify locations:

  CAfile: C:/Users/Seth/Documents/R/win-library/3.1/shinyapps/cert/cacert.pem

  CApath: 

Timing stopped at: 0.03 0 0.22 

`

I have never seen this before.  When I google around for it, I mostly find issues with MacBooks and firewalls and things that seem unrelated.  I can't seem to find any threads about these sorts of errors in shiny.

I'm sort of at a dead end for how to fix this.  Any help would be greatly appreciated.

I'm using:

Windows 7

RStudio Version 0.98.978 

R Version 3.1.1

I downloaded the most recent version of shiny with devtools and tried it again, but got the same error

Can you try reinstalling RCurl and shinyapps packages?

No luck.  Just tried the following:

`

[Andy Kipp]

Does the file exist?

C:/Users/Seth/Documents/R/win-library/3.1/shinyapps/cert/cacert.pem

[Seth Green]

I does.  I found it and managed to open it in RStudio, but I can't seem to make much sense of it all.

Starts like this and then continues on to a bunch of certificates and tokens, etc.:

`

##

## ca-bundle.crt -- Bundle of CA Root Certificates

##

## Certificate data from Mozilla as of: Sat Dec 29 20:03:40 2012

##

## This is a bundle of X.509 certificates of public Certificate Authorities

## (CA). These were automatically extracted from Mozilla's root certificates

## file (certdata.txt).  This file can be found in the mozilla source tree:

## http://mxr.mozilla.org/mozilla/source/security/nss/lib/ckfw/builtins/certdata.txt?raw=1

##

## It contains the certificates in PEM format and therefore

## can be directly used with curl / libcurl / php_curl, or with

## an Apache+mod_ssl webserver for SSL client authentication.

## Just configure this file as the SSLCACertificateFile.

##

# @(#) $RCSfile: certdata.txt,v $ $Revision: 1.87 $ $Date: 2012/12/29 16:32:45 $

`

Any thoughts on what to do with that would be much appreciated!

Thanks,

Seth

[Seth Green]

Andy or anyone else,

Any other ideas on what to try?  I'm really hitting a brick wall here and I have to deploy this App fairly soon.

Any help is mostly greatly appreciated.

Seth

[Andy Kipp]

Seth,

Did you restart R after upgrading RCurl?

-Andy

[Seth Green]

Yes.  Restarted the whole computer in fact.  Any thoughts on what to do with that file it references?  Should I delete it and then see if shiny automatically downloads a new one when I try to run it?

Should I uninstall shiny altogether?

thanks,

S

[Andy Kipp]

The file defines a certificate authority list for the RCurl package. 

You can try replacing the file with the one from:

http://curl.haxx.se/ca/cacert.pem

Also make sure the file has permission to be read.

-Andy

[Seth Green]

Yes, I just tried to replace it with that one and the same issue happened.  I checked and the security seems like I'm allowed to read and execute and everything.  I'm staring at this error, just wondering what it could mean:

Error in function (type, msg, asError = TRUE)  :

  CApath:

Is there something obvious I'm missing?  The path is right.

When I click on Tools -> ShinyApps it shows me as a connected user.  Then I tried to just click Deploy App through that menu and got (almost) the same error.

[Seth Green]

OK, I've tried a few more things are still get the same error:

I uninstalled shiny and shinyapps with remove.packages(), then reinstalled

I logged out on my computer and logged back in as the administrator.  Tried it there, same error.

I opened a new shinyapp.io account so that I'd have a different token.  Same error.

I have not yet tried uninstalling RStudio from my computer and then reinstalling, but I'm tempted to go that far.  

Any other thoughts on what could be the issue or should I just give that shot?  Any kind of global settings on my computer that could be screwing it up?  It's a Dell Vostro 3450, i5 processor, running Windows 7.

S

[Seth Green]

Holy shit, I fixed it with one line of code:

options(RCurlOptions = list(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl")))

I'm not even sure what that means, but it was on a discussion board about someone getting a similar error when they tried to get stuff off of Twitter on a mac.  They said, "I tried this code that was supposed to work for Windows, but it didn't work for me."

I tried it anyway and it work.  Hallelujah.

Thanks for all of you help.

[Andy Kipp]

Seth, Glad you got it working I was pretty stumped. 

Can you send the following to see if we can track this down:

R Version

R Studio Version

RCurl Version

ShinyApps version

Thanks

-Andy

[Seth Green]

Andy,

Thanks for looking into that.

I'm using:

Windows 7

RStudio Version 0.98.978 

R Version 3.1.1

I reinstalled shinyapps and shiny and RCurl during this whole fiasco and nothing changed so I guess I'm using the most recent version of all of those.

Best of luck and thanks again for all the help.

Seth
