Hey everyone, this is a known bug. branchName is ignored when autoBranch: true, and when autoBranch: false it breaks autoCreatePr. From the screenshots, even with the right parameter combo, the branch still gets created with an auto-generated name.
The team is aware and the bug is logged. Sadly there’s no ETA for a fix yet, but the number of reports here and in this other thread helps with prioritization.
I’ll update the thread as soon as there’s news.
