Error Message: "Github API: Not Found"
Codecov uses the code provider's API with your token to determine if we should allow access to pages regarding your repositories. One of the most common reasons for this API check to fail is that you have not granted Codecov access to your private repositories or orgs.
The following article has more information regarding this as well as steps to grant this additional access if needed: https://codecovpro.zendesk.com/hc/en-us/articles/15822167045403-Cannot-access-repository-on-Codecov-Permissions-
Additionally, you can verify that your admin had granted Codecov access to your org by checking the settings under third party restrictions. More details about this here: https://docs.codecov.com/docs/github-oauth-application-authorization
