Routing issue while upgrading NativeScript version 7 to 8

Issue Description

Our project is based on Native Script 7. We are transferring it to nativescript 8, we are facing routing issue. We are using this method for routing from navigate one page to another.

this.routerExtensions.navigate(["search/licenseplate-search"], { relativeTo: this.activatedRoute, }),

When we come back from that page. we use this method
this._routerExtensions.back({ relativeTo: this._activatedRoute, });

We are getting this error when we come back by clicking on the back button.

CONSOLE ERROR: ns-router: No outlet found relative to activated route
