Auth module doesn't fetch user after logged in (laravelSanctum)

[robingiraud]

Hello everyone,
I have a problem using the AuthModule with laravelSanctum, only when the backend is built in production (hosted in an Heroku server).

My problem is : I can login well with this.$auth.loginWith('laravelSanctum', ...) but then, the endpoint to fetch user's data isn't called.
When I set up my nuxt.config.js to fetch my local api, everything is ok. But when I setup to fetch the API in production mode, I'm having this problem.
I think I've tried everything for the last 2 days, so I hope someone could help me :)

Here is my nuxt.config.js :

strategies: {
      laravelSanctum: {
        provider: 'laravel/sanctum',
        token: {
          property: 'token',
          global: true,
          required: true,
          type: 'Bearer'
        },
        refreshToken: {
          required: false
        },
        url: 'https://myapp.herokuapp.com',
        endpoints: {
          login: {
            url: '/api/login',
            method: 'POST'
          },
          logout: {
            url: '/api/logout',
            method: 'GET'
          },
          user: {
            url: '/api/user',
            method: 'GET'
          }
        },
        user: {
          property: false
        }
      },
      cookie: {
        token: {
          property: 'token', required: true, type: 'Bearer'
        },
        endpoints: {
          csrf: {
            url: 'https://myapp.herokuapp.com'
          }
        }
      }
    }

I also test the hosted API with Insomnia, and every endpoint is ok

Thanks for your help :)
