branch_copy(checkout=True) liefert ungültigen Projekt-Handle (0) in CODESYS V3.5 SP22 Patch 3

Since upgrading from V3.5 SP21 P3 to SP22 P3, this previously working scripted call fails:

project, current_branch = project.git.branch_copy(current_branch,new_branch_name,checkout=True)

Error:

_3S.CoDeSys.Core.Objects.InvalidProjectHandleException
Standard Error: The project handle 0 is invalid

Workaround:

When you do branch copy with checkout=False and then checkout the branch in a seperate line everything works. The issue seems to be that Codesys doesn't give back a proper handle when you do branch_copy with checkout=True.

This is mainly so that issue gets noted and resolved in a further Patch and that people with the same issue might have an easier time debugging their scripts.

With kind regards
