CopilotKit runtime failures prevent agent replies when SSE streaming stalls or the agentId is mismatched. Diagnosing the issue requires inspecting the info endpoint, tracing AG-UI event flow, and verifying model configuration to isolate where the run stalls.

Debug CopilotKit runtime connectivity by verifying the runtime URL, base path, CORS setup, and discovery endpoint. Trace AG-UI SSE events to find where the stream stalls, and inspect package versions to identify mismatch issues causing the connection failure.

Fix CopilotKit tool execution errors by isolating frontend tool registration issues and checking for malformed tool arguments. Inspect handler exceptions within the runtime configuration to determine why the tool fails during the agent run.

Version mismatch issues in CopilotKit applications occur when package versions are incompatible across the runtime and client. Inspecting package versions and runtime configuration reveals the conflicting dependencies causing agents and streams to fail.

Resolve CopilotKit voice transcription failures by inspecting the runtime configuration and tracing the AG-UI event flow. Isolate the transcription component to identify whether the failure stems from handler exceptions or agent connection drops.

Tracing AG-UI events isolates where a CopilotKit agent run stalls by following the SSE stream from the registered agent. Comparing the active agentId against registered agents and checking error codes pinpoints the exact failure point.
