The action cache is always null

I’m trying to add user permissions to id token. This scripts works fine except for cache. The cache is always null. I tested this action in flow too. What am I doing wrong?

exports.onExecutePostLogin = async (event, api) => {
  const ManagementClient = require('auth0').ManagementClient;
  const jwt_decode = require('jwt-decode');
  const axios = require('axios');

  // Fetch cached token
  const cachedTokenRecord = api.cache.get('token');
  let token = cachedTokenRecord?.value;
  const currentTime = Date.now().valueOf() / 1000;

  let management;

  if (token) {
    console.log("Found cached access token.");

    const decodedToken = jwt_decode(token);

    if (decodedToken.exp > currentTime) {
      management = new ManagementClient({
        token: token,
        domain: event.secrets.AUTH0_DOMAIN,
      });
    }
  }

  if (!management) {
    try {
      const response = await axios.post(`https://${event.secrets.AUTH0_DOMAIN}/oauth/token`, {
        client_id: event.secrets.AUTH0_CLIENT_ID,
        client_secret: event.secrets.AUTH0_CLIENT_SECRET,
        audience: `https://${event.secrets.AUTH0_DOMAIN}/api/v2/`,
        grant_type: 'client_credentials'
      });

      let newToken = response.data.access_token;

      const cacheResult = api.cache.set('token', newToken);

      if (cacheResult.type === 'error') {
        console.error('Failed to set the token in the cache:', cacheResult.code);
      } else {
        console.log('Successfully set access token in cache');
      }

      management = new ManagementClient({
        token: newToken,
        domain: event.secrets.AUTH0_DOMAIN,
      });

    } catch (error) {
      console.error('Error fetching new access token:', error);
      throw new Error('Error fetching new access token');
    }
  }

  try {
    const params = { id: event.user.user_id, page: 0, per_page: 100, include_totals: true };
    const permissions = await management.getUserPermissions(params);

    const permissionsArr = permissions.permissions.map(permission => permission.permission_name);

    api.idToken.setCustomClaim(`${event.secrets.NAMESPACE}user_authorization`, {
      permissions: permissionsArr
    });
  } catch (err) {
    console.error('Error fetching user permissions:', err);
    throw new Error('Error fetching user permissions');
  }
};
