route_prefix crashes the next and nuxt generators

[CedCannes]

API Platform version(s) affected: 2.6.6

Description
the next and nuxt generators return an error if routePrefix is set

How to reproduce
Add the routePrefix parameter to the apiResource attribute of an entity.

#[ApiResource(
    routePrefix: "prefix"
)]
class Board

or in the api/config/packages/api_platform.yaml file

# Good cache defaults for REST APIs
    defaults:
        stateless: true
        cache_headers:
            vary: ['Content-Type', 'Authorization', 'Origin']
        route_prefix: prefix

Possible Solution

Additional Context
The error appeared for next and nuxt but not the other generators.

the error :

I see the same error if I change new Resource("abc"... by new Resource("prefix/abc"... in the unit test here
