This error message usually occurs when you try to add a child component to a parent component multiple times. To fix this error, you need to check the code where the gdcomponent is added to the parent component and make sure that it's only added once.
One way to prevent this error from happening is to remove any previous instances of the gdcomponent from the parent component before adding a new one. You can do this using the `removeChild()` method of the parent component, like this:
```
// Remove any previous instances of gdcomponent
if (parentComponent.contains(gdcomponent)) {
parentComponent.removeChild(gdcomponent);
}
// Add gdcomponent to parent component
parentComponent.addChild(gdcomponent);
```
Make sure to replace `parentComponent` and `gdcomponent` with the actual names of your components.
