name: moving Bandada's vkey inside cloud function
about: Open a PR for p0tion

Description

We are having some issues when trying to deploy the cloud functions in our production environment. According to a Firebase team comment in a Github issue, it might be related to having large data and actions in the global scope instead of inside the function (check comment here).

Fixes # (issue)

How Has This Been Tested?

I have not been able to test it due to the fact that the function deployment in prod environment happens when we merge the respective PRs.
