To group your cli projects, Snyk looks for a .git/config file that is placed there by git.
If Snyk finds the .git/config file, Snyk uses the remote_url value as the key, and a child file from the repository is used to provide the project grouping context. Otherwise Snyk is not able to link together different projects that have been monitored using the Snyk CLI monitor command.
Ensure you are running an up-to-date version of the CLI, and have run snyk monitor.
