Why message "Session 1 in secondary port (1/7) of this LAG: Deploy Failed" when deploying a MLX lag

When attempting to deploy a LAG between 2x MLXe routers, we received the following message:


"Session 1 in secondary port (1/7) of this LAG: Deploy Failed".


The primary link had been in service with no issues. There was also OSPF and EBGP running across the primary link but had brought down BGP before attempting to deploy. Was able to deploy from the other side but lost connectivity. Performed "no deploy" and link came back up.
