Collection contains more than one matching element.
See original GitHub issueI was looking into the sample project that you have inside the repository. Sometimes the project fails to build with the following error. If i do a clean build, then everything works as expected.
Steps to reproduce:
- Make some change in the
LoggedInComponent, like a typo or something - Build fails because what you typed is not correct, this is OK
- Revert the change, now the branch is exactly the same as the main
- build again, project build should fail
- If it doesn’t fail try again the above steps…
- Do a clean build and the project will build fine.
For me personally this issue is happening quite often… Stacktrace
