How to initialize two Harbor instances?

Hi all!
I'm trying to write replication test between two Harbor instances. I tried to create them like this:
```
const harbor1 = new Harbor(settings.Harbor1)
const harbor2 = new Harbor(settings.Harbor2)
```
but when I run my test I got an error:
```
goerror: harbor module initialized
```
How I can solve this issue?

No file or test entry point is named. Start by tracing the Harbor constructor and the source of the “harbor module initialized” error, then inspect how the replication test creates its instances. Done means the test can initialize two Harbor instances with separate settings without that error.
