Describe the issue

After upgrading Automapper to v8 and fixing all the breaking changes, my application is returning error of maximum call stack size at ApplyMetaData.

My jest unit tests are also not running and returning mapping between class A and class B cannot be found error even though there are mappings present and injected as well.

See image below of the code.

The mapper returned by the createMapper is not actually the empty proxy and produces the below error when running tests.

Expected behavior

It should return the mapper instance and not give maximum call stack error and should get the mapping as defined.
