Good afternoon!

I am trying to deploy deduplication-web-api using docker container registry.creatio.com/dup-web-api:3.0.12

I see this problem in the logs.

fail: Microsoft.AspNetCore.Server.Kestrel[13]
     Connection id "0HN5FOGURGKI1", Request id "0HN5FOGURGKI1:000000E2": An unhandled exception was thrown by the application.
     System.InvalidOperationException: Synchronous operations are disallowed. Call WriteAsync or set AllowSynchronousIO to true instead.
        at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.HttpResponseStream.Flush()

        at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.HttpProtocol.ProcessRequests[TContext](IHttpApplication`1 application)

appsettings.json looks like this:

Can you please tell me what the problem could be?
