Why GitLab pipeline stays in "Checking pipeline status"?

Hi Folks! I create a GitLab Pipeline in order to check the **Lighthouse** between two branches.

*This should be the rules:*

* *Doesn't run if you push something into* ***main*** *branch*
* ***Only works*** *when you perform a* ***merge request***
* ***Only should work IF*** *you are doing a* ***merge request to main branch,*** so, *it should't work if you try to merge dev-2 into dev*

**The problems happends when** i try to do a merge request from *dev-2 into dev...*
If you go to this merge request: [https://gitlab.com/RicardoRien/lighthouse\_pipeline/-/merge\_requests/9](https://gitlab.com/RicardoRien/lighthouse_pipeline/-/merge_requests/9)

you can see, that **stays in a infinite load spinner with this message "Checking pipeline status."**

Do you know why? Thanks in advance!
