We are done with all cumulusCI configuration set up, Now we are using MetaCI CLI v0.1.4 to run these same builds against your project automatically on Heroku. We are successfully deploying a new MetaCI site on Heroku using free dyno resources.
Now we are stuck in "Adding the Repository to MetaCI" section during metaCI implementation and we have the following execution with an exception:

coreapi.exceptions.LinkLookupError: Index ['repos']['list'] did not reference a link. Key 'repos' was not found.

Note: We are using 'metaci repo add' or 'metaci repo list' command to adding the repository to metaCI.

Thank you,
