Heroku and Sentry integration

I installed the SDK using pip install and did the post hook install.
I need to select repositories in the integration process.
My Herkou Git repo is https://git.heroku.com/miglinux19.git
How to enter it in the “select the repositories” field.

I tried the following:

git.heroku.com/miglinux19.git
miglinux19.git/myname
miglinux19/myname

But, none of them worked.
Could someone please help me.
I am stuck at this step for the past 2 days.
Thanks for your helpin advance
BM
