The syntax for the “apollo” options you listed do indeed look correct- assuming you’re intending to use the package “vue-apollo” to work with Apollo.
If you’re getting this error it may mean that “vue-apollo” hasn’t been installed, or there’s some problem with the installation.
If you look in the Vue Chrome debugger tool on one of your pages, is the “$apollo” property present in all your components? If not, the issue is that the “vue-apollo” plugin hasn’t been properly installed.
