The dependencies of the transient service are injected correctly.

Other information

Disclaimer: the fix was made by an LLM. I simply provided the .spec.ts file and asked it to fix it, I don't understand NestJS deeply enough to understand the fix fully.

Besides that, I didn't know where I should place the test file, open to suggestions if the current place is unfitting 😄
