Moving r app from shinyapp to linux server and having config. errors

...Error in config::get("datawarehouse", file = "config.yml") :
Config file config.yml not found in current working directory or parent directories

this is the error that I received upon migrating my r.shiny app on to our Linux server. The config file was in the folder that I dropped into the server. The actual file path also hasn't moved. So I am unsure what else to change.

Any help is appreciated !
