Sometimes you get this error when you try to use a component from a module, which is not shared, in a different module.

For example, you have 2 modules with module1.componentA.component.ts and module2.componentC.component.ts and you try to use the selector from module1.componentA.component.ts in a template inside module2 (e.g. ), it will throw the error that the someInputVariableInModule1 is not available inside module1.componentA.component.ts - even though you have the @Input() someInputVariableInModule1 in the module1.componentA.

If this happens, you want to share the module1.componentA to be accessible in other modules. So if you share the module1.componentA inside a sharedModule, the module1.componentA will be usable inside other modules (outside from module1), and every module importing the sharedModule will be able to access the selector in their templates injecting the @Input() declared variable.
