You can simply send the exception details to the client by enabling one of ABP's configurations (SendAllExceptionsToClients) in ***.Web.Core Module, like this:

public override void PreInitialize()
{   
    Configuration.Modules.AbpWebCommon().SendAllExceptionsToClients = true;
}

Then you get the exception details on the client. Recommended only during development.
