In environments running 2026.1, we are experiencing an issue with button logic created in user events. Specifically, these buttons make an HTTPS call to a Restlet that returns text, which is then used to generate and download a file in the browser. When the button is clicked, the call to the Restlet results in a 500 error. The same bundle works correctly in a 2025.2 environment with the same bundle version and identical code.
