route validation method not called

Hello, I am currently stuck at the validation method on a page in my project. I try to validate the route based on a http request. I tried to return false right away in the validate() method, but still nothing happens. I also can not see console.logs i wrote in that function. Here is my code: 
definePageMeta({
    validate: async (route) => {
        var spaceId = route.path.substring(route.path.lastIndexOf('/') + 1);

        var validity = false

        await $fetch(`${runtime.public.apiUrl}/spaces/${spaceId}`, {
            method: 'GET',
            onResponse: (response) => {
                if (response.response.ok) {
                    validity = true
                } else {
                    validity = false
                }
            }
        })

        return validity;
    }
})
definePageMeta({
    validate: async (route) => {
        var spaceId = route.path.substring(route.path.lastIndexOf('/') + 1);

        var validity = false

        await $fetch(`${runtime.public.apiUrl}/spaces/${spaceId}`, {
            method: 'GET',
            onResponse: (response) => {
                if (response.response.ok) {
                    validity = true
                } else {
                    validity = false
                }
            }
        })

        return validity;
    }
})

Hi @Leander. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information provided in the knowledge sources, I can help you with your issue regarding the route validation method in Nuxt. It seems that you're experiencing a problem where the validate function in definePageMeta is not being called or executed as expected. There are a few things to consider: 1. First, make sure you're using Nuxt 3, as the syntax you're using is specific to Nuxt 3. 2. The validate function in definePageMeta should be working as you've described. However, there have been some issues reported with definePageMeta in certain Nuxt versions. 3. According to the Nuxt documentation on route validation, the validate property accepts the route as an argument and should return a boolean value or an object with statusCode/statusMessage to respond immediately with an error. Here are some suggestions to troubleshoot and potentially fix your issue: 1. Try updating to the latest version of Nuxt if you haven't already. There have been fixes related to definePageMeta in recent versions. 2. Instead of using an async function with await, try using a promise-based approach: 
definePageMeta({
  validate: (route) => {
    const spaceId = route.path.substring(route.path.lastIndexOf('/') + 1);
    
    return $fetch(`${runtime.public.apiUrl}/spaces/${spaceId}`, {
      method: 'GET'
    })
      .then(response => {
        console.log('Validation response:', response);
        return true; // or false based on your validation logic
      })
      .catch(error => {
        console.error('Validation error:', error);
        return false;
      });
  }
});
definePageMeta({
  validate: (route) => {
    const spaceId = route.path.substring(route.path.lastIndexOf('/') + 1);
    
    return $fetch(`${runtime.public.apiUrl}/spaces/${spaceId}`, {
      method: 'GET'
    })
      .then(response => {
        console.log('Validation response:', response);
        return true; // or false based on your validation logic
      })
      .catch(error => {
        console.error('Validation error:', error);
        return false;
      });
  }
});
3. If you're still not seeing console logs, there might be an issue with how the validation function is being executed. You could try adding a console.log statement at the very beginning of the function to see if it's being called at all. 4. If none of the above work, you might want to consider using a middleware function instead. Middleware functions are more flexible and might be easier to debug. You can create a named middleware in the middleware/ directory and use it in your page: 
// middleware/validateSpace.js
export default defineNuxtRouteMiddleware((to) => {
  const spaceId = to.path.substring(to.path.lastIndexOf('/') + 1);
  
  return $fetch(`${runtime.public.apiUrl}/spaces/${spaceId}`, {
    method: 'GET'
  })
    .then(response => {
      console.log('Validation response:', response);
      // Your validation logic here
    })
    .catch(error => {
      console.error('Validation error:', error);
      return navigateTo('/error');
    });
});

// In your page component
definePageMeta({
  middleware: ['validateSpace']
});
// middleware/validateSpace.js
export default defineNuxtRouteMiddleware((to) => {
  const spaceId = to.path.substring(to.path.lastIndexOf('/') + 1);
  
  return $fetch(`${runtime.public.apiUrl}/spaces/${spaceId}`, {
    method: 'GET'
  })
    .then(response => {
      console.log('Validation response:', response);
      // Your validation logic here
    })
    .catch(error => {
      console.error('Validation error:', error);
      return navigateTo('/error');
    });
});

// In your page component
definePageMeta({
  middleware: ['validateSpace']
});
If you're still experiencing issues after trying these suggestions, it might be worth checking if there are any specific bugs or issues reported for your Nuxt version related to definePageMeta or route validation. For more information on route middleware and validation, you can refer to the Nuxt documentation on middleware. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
