How to select a webelement

[spchan]

Hi, I got the following error while using UFT 12.51 :

Cannot identify the object "Create branch:new_branch" (of class WebElement)

My code:

Code:

email_addr = "sp@xxx.com"
    pwd = "12Ka10##"
    repo = "shanti-testrepo"
    uid = "sp"
    new_branch = "branch8"

SystemUtil.Run "IExplore.exe", "https://github.com"

Browser("Sign in via LDAP · GitHub").Page("Sign in via LDAP · GitHub").WebEdit("login").Set "sp@xxx.com"
Browser("Sign in via LDAP · GitHub").Page("Sign in via LDAP · GitHub").WebEdit("password").SetSecure "568a9c124918796c14dda31b0d833acefa6c5089281f"
Browser("Sign in via LDAP · GitHub").Page("Sign in via LDAP · GitHub").WebButton("Sign in").Click
Browser("Sign in via LDAP · GitHub").Page("GitHub").Link("repo").Click
Browser("Sign in via LDAP · GitHub").Page("uid/repo").WebEdit("Find or create a branch…").Set new_branch
Browser("Sign in via LDAP · GitHub").Page("uid/repo").WebElement("Create branch: new_branch").Click

Any help is highly appreciated.
