I did also encounter that error yesterday but managed to fix it I am not home currently but let me check when I am back what my solution was But maybe I am also stupid and there really is something wrong I don't exactly remember what the error was yesterday here is my implementation i think the error is just that you need to remove the JSON.stringify from the get function: 
secondaryStorage: {
    get: async (key) => {
      const value = await redis.get(key);
      return value ? value : null;
    },
    set: async (key, value, ttl) => {
      if (ttl) {
        await redis.set(key, value, "EX", ttl);
      } else {
        await redis.set(key, value);
      }
    },
    delete: async (key) => {
      await redis.del(key);
    },
  },
secondaryStorage: {
    get: async (key) => {
      const value = await redis.get(key);
      return value ? value : null;
    },
    set: async (key, value, ttl) => {
      if (ttl) {
        await redis.set(key, value, "EX", ttl);
      } else {
        await redis.set(key, value);
      }
    },
    delete: async (key) => {
      await redis.del(key);
    },
  },
i am using ioredis btw but even if you do not that should fix it atleast i am not getting the error anymore
