In SkyWalking, each monitored component/framework will have a unique identifier. because of the publish time and publish version for the SkyWalking main project and nodejs project is not one by one corresponding. So some monitored component/framework identifier are not recognized by the SkyWalking Collector, it will cause some problems on the UI.
So you have two ways to resolve this problem. One is download the compatible version and the other way is add your own component library setting.

| 0.3.0 | 5.0.0-RC |
| 1.0.0 | 6.0.0-GA |
| 2.0.0 | 8.1.0 |
