Newly deployed app in existing infrastructure fails because of Status Code 500 with a String index out of range error

Hi folks,

Been using Shinyproxy to deploy some apps on AWS EC2, and have run into a strange issue when trying to add a new app to our existing infrastructure. The new app shows up in the Shiny Portal page, but when attempting to open it fails with a Status Code 500 and with a “Caused by: java.lang.StringIndexOutOfBoundsException: String index out of range: 12”.

The app works just fine standalone (I went through the suggestions in Shinyproxy troubleshooting guide on this) both locally and on EC2. The existing app continues to work in the existing infrastructure.

Any thoughts or ideas on this?


I think this error comes somewhere from parsing your configuration file.
Can you provide the full stack trace of the error and your application.yml file?
