"React error #31 when rendering workflow/node output objects ({text, type})”
While using SimStudio, the UI crashes with Minified React error #31 when rendering workflow or node outputs. This happens when a node (especially LLM or tool-based nodes) returns a structured object (for example, an object with keys like { text, type }). The UI appears to try rendering this object directly in JSX instead of rendering a string value (such as output.text) or iterating over the content. As a result, after the workflow state is received (via Socket.IO), the UI throws the error: “Objects are not valid as a React child (found: object with keys {text, type})” This seems to be a UI rendering issue rather than a workflow execution problem. Handling structured outputs safely (e.g., extracting text or mapping arrays) would prevent the crash.
