unable to setup properly under quasar 1.19.5 and vuejs 2.7

[talkonadmin]

1. When using previous quasar version with vuejs 2.6 I was able to setup properly using @vue/composition-api package
2. I am trying to upgrade to quasar 1.19.5 with vuejs 2.7 using the same code for initializing the client according to documentation but I keep getting the error: "Apollo client with id default not found. Use provideApolloClient() if you are outside of a component setup"
3. All my setup is done under the app component setup function exactly as described.

Any possible reasons for this error?

thx
