The bug was uncovered after updating React in Next.js in vercel/next.js#66711. The test fails with: ``` TypeError: Cannot read properties of undefined (reading 'children') 1003 | let value = chunk.value; 1004 | for (let i = 1; i < path.length; i++) { > 1005 | value = value[path[i]]; | ^ 1006 | } 1007 | const chunkValue = map(response, value); 1008 | if (__DEV__ && chunk._debugInfo) { at getOutlinedModel (packages/react-client/src/ReactFlightClient.js:1005:26) ```
