Hello , We have a dockerized served over aws ecs environment. Normally on local there is nothing wrong, it works successfully , but when we try on ecs environment below responses coming from file management download endpoint : the first request which takes the token , seems successfull , (By the way it says succesfull but the response seems empty over google inspect window ):

After that, second request to download with this (unseen over google inspect window) token ends like below:

Like I said we couldn't reproduce the same error on our local , why this token could not be authorized ? Can you help? Thanks.

    Hi,

    ABP uses distributed cache to store the download token.

    Is the Redis server available?

    We have a dockerized served over aws ecs environment.

    I think it must be related to the cache, different instances may use different Redis in the docker container.

    But in that case sometimes we should be able to download , sometimes not , right ? In our case we couldn't download even once. How should we check that if we have one redis ?

    Hi,

    How should we check that if we have one redis ?

    You can use the distributed cache to set some test data and read it:

    public class TestCacheItem
    {
        public string Value { get; set; }
    }
    
    public class TestCacheAppService : ApplicationService, ITestCacheAppService
    {
        private readonly IDistributedCache<TestCacheItem> _cache;
    
        public TestCacheAppService(IDistributedCache<TestCacheItem> cache)
        {
            _cache = cache;
        }
    
        public Task SetCacheAsync(string key, string value)
        {
            _cache.Set(key, new TestCacheItem { Value = value }, new DistributedCacheEntryOptions
            {
                AbsoluteExpirationRelativeToNow = TimeSpan.FromMinutes(5)
            });
            return Task.CompletedTask;
        }
        
        public async Task<string?> GetCacheAsync(string key)
        {
            var item = await _cache.GetAsync(key);
            return item?.Value;
        }
    }
    

    Is your Redis server running in a docker container or you are using Amazon ElastiCache for Redis Could you please share the dockerfile or docker-compose file and application log file? thanks
