You can access a Git repository by using either the SAS^® Studio 3.8 experimental interface or DATA step functions in Base SAS^®. The connection to the remote repository is specified by one of two authentication methods:

• SSH key authentication, which requires an SSH URL 
• HTTPS authentication, which requires an HTTPS URL  

When you use the SSH key authentication method with certain actions, which include cloning, pushing, or pulling files, you see an error. 

In the SAS Studio interface, the following pop-up error message is shown:

Using the DATA step functions GITFN_CLONE, GITFN_PUSH, and GITFN_PULL with SSH key authentication results in the same error in the program log file:

 

The workaround is to use the HTTPS authentication method for these actions.
