Error in Running KoboConnect.R Script

[moloscripts]

When I run the code chunks separately, the data finally downloads. However, when I put the script on Shiny apps or in a similar environment, and run the R-script, the download fails.

Any reason for this? (See screenshot)

Hi @moloscripts ,
Thanks for your continued support.
It is difficult for me to identify the exact issue. However, I feel that this is happening because the download URL takes a while to generate and R does not wait for the function to return value before executing the next line. In which case, there could be several approaches to take. For example, asynchronous. Or, have a look at some of the ways at

For the sake of simplicity, I would take another approach. I would run a cron job that downloads data at regular intervals and feed the downloaded data to the shiny app. This way, the shiny app will not execute the API call, but will use the downloaded data.
Hope this helps.
