Unhandled Exception: 'NoneType' object has no attribute 'lower'

[pablobernabeu]

I would like to request help with an error arising when deploying an rmarkdown-Shiny app to shinyapps.io, from RStudio Cloud. The app does run locally well. It also used deploy to shinyapps.io until very recently. Moreover, the app is deploying well to shinyapps.io from Desktop RStudio. Therefore, the issue seems specific to RStudio Cloud.

I've searched a lot but haven't found a solution. Please find the code and the error below.

Code: https://raw.githubusercontent.com/pablobernabeu/Modality-exclusivity-norms-Bernabeu-et-al/master/Shiny-app/Dutch-modality-exclusivity-norms.rmd

Error:

Preparing to deploy document...DONE

Thank you very much

Hi there,

I dug into this a bit, and there is something weird going on with the "survival" package. For some reason the rsconnect package was unable to detect the package source, which is causing an error in our system.

Can you run packageDescription("survival") and send me the output?

Thanks
-Andy

Hi Andy,

Thank you very much. I've just tried to deploy now, without changing anything or running packageDescription("survival"), and the deployment has been successful. I reckon something must have been changed in the server.

Regardless, the output I get from packageDescription("survival") is below:

Hi,

Thats really interesting. I'm glad to hear its working now. It's possible there was something going on with our package server. I am noting the following in the description that says the package was recently built.

Built: R 3.6.0; x86_64-pc-linux-gnu; 2020-02-23 03:07:17 UTC; unix

I will ping some folks internally to see if they have any insight. I will keep you posted.

Thanks a lot
