need help, can't understand what's wrong with the error

[v1k70rk4]

Hi, I don't know if you are developing, but run the script/lint script on the files. Lint wants to fix something in the file (an extra space or an incorrect indentation) in the sentences/el/cover_HassGetState.yaml file, and that's why the tests are not running.

If you have already done this and there is still an error, then update the repository and run the script/setup again.

Because there hasn't been any activity on this PR for quite some time now, I've decided to close it for being stale.

Feel free to re-open this PR when you are ready to pick up work on it again 👍
