Review Comment:
**Scalability Issue**: Null check for 'registryConfig' in the lambda
expression improves the robustness of the system by preventing potential
NullPointerException in scenarios where the registries list might contain null
elements. <br> **Fix**: Add null check for 'registryConfig' before accessing
its methods to prevent potential NullPointerException. <br> **Code
Suggestion**:
```
- if (registryConfig.getScopeModel() != applicationModel) {
+ if (registryConfig != null &&
registryConfig.getScopeModel() != applicationModel) {
```
