+Component parameters can only receive query parameter values in routable components with an @page directive.
+
+== Why is this an issue?
+
+https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.components.supplyparameterfromqueryattribute[SupplyParameterFromQuery] attribute is used to specify that a component parameter of a routable component comes from the https://en.wikipedia.org/wiki/Query_string[query string].
+
+In the case non-routable components the `SupplyParameterFromQuery` does not contribute to the functionality and removing it will not affect the behavior.
+
+== How to fix it
+
+Either make the component routable or remove the `SupplyParameterFromQuery` attribute.
