igc pipeline - is not working in OCP. It throws “Error registering pipeline” error.

**Describe the bug**
When i use, igc pipeline -n dev-gan-2, it was throwing an error “Error registering pipeline: Cannot read property 'jenkinsUrl' of undefined”

After some debugging, I resolved the problem. The main issue was that the git login was pointing to my old user id. I cleared the old user from Keychains and it started working.

The igc cli should have given the right error message, when there is a git login issue.

igc version 0.4.14
npm version 6.14.4
node version v13.12.0

**To Reproduce**
Jeyas-MacBook-Pro:dev-gan-04-test1 jeyagandhi$ igc pipeline -n dev-gan-2
? Select the type of pipeline that should be run? Jenkins

**Expected behavior**
