Error: “Maximum call stack size exceeded” and 408 Request Timeout
We are currently developing a custom AppFoundry application that requires dynamic script injection into the Genesys Cloud Agent Desktop to facilitate real-time data synchronization between our external CRM and the active interaction context. The goal is to update custom attributes on the fly without requiring a full page refresh or a manual trigger from the agent.
The implementation involves using the genesys-cloud SDK to listen for interaction events and subsequently injecting a lightweight JavaScript snippet into the DOM. This snippet communicates with our backend service to fetch updated records. However, we are encountering significant stability issues when the injection frequency exceeds 500 milliseconds. The browser console logs a “Maximum call stack size exceeded” error, followed by the widget crashing and returning a 408 Request Timeout from the Genesys Cloud platform API when attempting to re-initialize the connection.
Our current approach utilizes the window.postMessage API to bridge the gap between the iframe and the host application, but it appears that Genesys Cloud’s security sandbox imposes strict limitations on how often external scripts can be evaluated or injected. We have reviewed the AppFoundry developer documentation, but it lacks specific guidance on rate limiting for DOM manipulation or script injection within the Agent Desktop environment.
Is there a recommended pattern for handling high-frequency data updates in this context? Should we be leveraging a different mechanism, such as WebSockets with a dedicated polling interval, to avoid triggering these stack overflow errors? Additionally, are there known constraints on the size of the payload being injected via the script tag that might be contributing to the 408 timeouts? We are operating in a multi-tenant environment, so any solution must be scalable and not rely on tenant-specific configurations that would hinder our deployment across different clients.
