Running a shiny app with multiple folders served on shinyapps.io. The app has a function which pulls data from S3 (using a wrapper around get_bucket()), which works fine locally as I set the AWS secret and credentials in my project .Renviron file, but once pushed I get a HTTP 403 error:

Error in value[[3L]](cond) : Forbidden (HTTP 403).
Calls: local ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous>
Execution halted

Things I have tried:

  • including the aws key, secret, and region directly in the get_bucket() call
  • changing bucket setting in aws to "open access"
  • setting the credentials in global.R file which includes sys.setenv()
  • adding a .Renviron to the main project folder with the credentials
  • Adding the credentials in the server.R file (to test, for confidentiality I don't want to do this)

I'm completely out of ideas on this one. It stems into a broader question of how to set .Renviron variables in a shinyapps.io app. Things I've read say to add to the main folder or other options, but as I say above hasn't worked.

I am reading the data in with shiny::reactivePoll() but don't see how this is the issue.

Thanks for your help, been stuck on this for days.

So, all along, the answer was in directly calling Sys.getenv() in the get_bucket()

get_bucket(s3BucketName,
                       "AWS_ACCESS_KEY_ID" = Sys.getenv("AWS_ACCESS_KEY_ID"),
                       "AWS_SECRET_ACCESS_KEY" = Sys.getenv("AWS_SECRET_ACCESS_KEY")

Which could call on the .Renviron I had in the main directory. I think in my previous attempts I had either a) not called on it correctly with Sys.getenv() or forget to address it properly.
