Why is this routing mismatched? - symfony

Question

A page contains this route: <a href={{ path('app_gut_food_vector') }}> but triggers a not found by the #ParamConverter annotation error. The log shows this: Matched route "app_gut_show". . I cannot figure out how this could be. My question: How to get the correct route matched?
Pieces of the puzzle:
log entry:
INFO 23:53:50 request Matched route "app_gut_show".
{
"route": "app_gut_show",
"route_parameters": {
"_route": "app_gut_show",
"_controller": "App\\Controller\\GutController::show",
"id": "vector"
},
"request_uri": "http://diet/gut/vector",
"method": "GET"
}
template includes:
Click <a href={{ path('app_gut_food_vector') }}> here</a>
Controller includes:
#[Route('/vector', name: 'app_gut_food_vector', methods: ['GET', 'POST'])]
public function vector(Request $request, GutRepository $gutRepository, VectorService $vectorSvc)
{
...
}
debug:router includes:
app_gut_index GET ANY ANY /gut/
app_gut_new GET|POST ANY ANY /gut/new
app_gut_show GET ANY ANY /gut/{id}
app_gut_edit GET|POST ANY ANY /gut/{id}/edit
app_gut_delete POST ANY ANY /gut/{id}
app_gut_food_vector ANY ANY ANY /gut/vector
and the incorrectly matched route:
#[Route('/{id}', name: 'app_gut_show', methods: ['GET'])]
public function show(Gut $gut): Response
{
...
}
Note: removing the methods from the vector method does NOT prevent the mismatch.

Answer 1

Depends on what symfony version you use, you could try to define route priority.
If you use older version than 5.1, try to move your annotaion to yaml file and define /gut/vector route higher than /gut/{id} route
For higher version view Symfony doc

Answer 2

I think you're somehow messing with route orders.
As a matter of fact /gut/vector matches also /gut/{id} as regex are used to match routes.
I think you should declare your routes (so controller methods) in other order to avoid this kind of collisions.
Alternatively you can ask esplicitly for id to be an integer (if it is an integer; if it is a UUID, just to pick one random example, you should stick to UUID format).
