Environment

Release : 12.3

Component : AUTOMATION ENGINE

Resolution

In the Automation Engine filesystem for that client, there is a folder structure of /bin/ae-filesystem/<client number>

Delete (or backup) any contents within the client encountering the error and re-initialize the client. 

Additional Information

The steps to remove the GIT connection from a particular One Automation Client are:

1. Remove the variables REMOTE_REPOSITORY_URL  and REPOSITORY_SSH_DIR from UC_CLIENT_SETTINGS in the impacted Client

2. Remove the subfolder '/one_automation_folder/bin/ae-filesystem/<client>'

3. Delete the line from the database table UC_REPO where REPO_CLIENT=<client>

 

Then, when desired, update again the variables in UC_CLIENT_SETTINGS and go the Version Control again where it will ask you to initialize the client.
