TypeError can't convert undefined to object

[JS-VG24]

Is there an existing issue for this?

Describe the issue

Hej there,

it seems this project is not maintained anymore, which is quite sad as I having trouble with an Issue I'm confronted with right now. I will post it anyways in the hopes there will be a fork and the Issue gets resolved there!

I have a project that uses Database Entities with Snake-Case and Dto's with Camel-Case. This worked fine until I defined multiple fields starting with the same string like:

password and password_reset_token

then all hell brakes loose and the following error is thrown:

TypeError can't convert undefined to object hasProperty@https://2vqzsn.csb.app/node_modules/ automapper/core/index.js:1120:42 getFlatteningPaths@https://2vqzsn.csb.app/node_modules/ automapper/core/index.js:1111:32 processSourcePath@https://2vqzsn.csb.app/node_modules/ automapper/core/index.js:1352:22 _loop3@https://2vqzsn.csb.app/node_modules/ automapper/core/index.js:1277:39 createInitialMapping@https://2vqzsn.csb.app/node_modules/ automapper/core/index.js:1315:17 createMap@https://2vqzsn.csb.app/node_modules/ automapper/core/index.js:1413:13

I made a simple CodeSandbox example that shows the problem and how to reproduce it.

Hopefully that will help!
