Error Message - Method not found: 'System.Data.Entity.Migrations.Builders.TableBuilder`1 System.Data.Entity.Migrations.Builders

I have a web api running on 2 servers (server01 and server02) with a load balancer. The api is pointing to the same database server.

This run ok on server01 but getting this error on server02.
