at interface based service Client side access violation error

hi;

Firstly, sorry for my bad english and this long post
I am newbie delphi and mormot.
I am playing some sample app with mormot.
I make some minor modification Samples\ThirdPartyDemos\George\REST-tester  app.
My app is interfacebased and  I have got many interfacebased functions over than 130.
So I made same change server and client side for this functions I make sections (make groups) over this functions.
For example; Customer, Bank, Crm etc.

HttpServer/Client start without any authentication (using http_Socket)
All of Server functions working with tested using Postman (http:/localhost:9031/...Methods/Function_name)
I haven't got any error at the server side.
in the client VCL program (At the Client side) sometimes has got error access violation at line
   TSQLRestClientURI.Services.Resolve(I...Methods, ...Methods);

Changed server section to working multiple TSQLRestServer with TServiceFactoryServer
like this

Where is the exact location of the access violation in mORMot source?

My guess (which is likely to be wrong) is that your local service interface variable like CustomerMethods are not properly released before assignment.

Thanks AB for your great support. I find that I didn't assign nil to child object of Client.
