I keep encountering the message 'Invalid type of argument: string cannot be assigned to a parameter of type never' within the useNavigationBuilder.tsx file. What could be causing this issue?

      if (route?.name) {
        routeNames.push(route.name);
      }
    } else {
      route = state.routes[state.index];
      routeNames.push(
         ...Object.keys(screens).filter((name) => route?.name === name)
      );
    }

An unexpected error has appeared in a file I did not modify during the creation of my React Native application, leading to confusion.

Answer №1

When encountering this issue while pushing, it is important to carefully review the typings for routeNames.

A possible scenario could be when your routeNames are defined with an interface or type similar to:

ExampleType = { name:string, id:number}

In this case, using a .push({name, string}) will function as expected.

However, if you opt to use a spread operator (...), there might be unintended consequences where other attributes get added to your object leading to a never type mismatch.

For instance, attempting to push an object containing name, id, path, and more into ExampleType would result in the same error due to these additional attributes not being part of the object's structure.
