firebase functions:config:set fails with uppercase environment variables

[tfesslerCWC]

• Operating System version: Macos 10.14.4
• Firebase SDK version: 6.9.1
• Node JS Version: 8.16.0
• Firebase Product: functions

Description:
UPPER CASE characters are required for some environment variables from some GOOGLE API's. The current version of the firebase admin for node prevents the use of uppercase characters.

Setting this configuration:
firebase functions:config:set GOOGLE_APPLICATION_CREDENTIALS="/Users/mickeymouse/functions/promotions-google-services.json"

Results in this error:
Error: Invalid config name GOOGLE_APPLICATION_CREDENTIALS, cannot use upper case

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

You're in the wrong repo. Function SDK and the associated tooling are in https://github.com/firebase/firebase-functions and https://github.com/firebase/firebase-tools

AFAIK the functions:config:set is not meant to be used for regular environment variables. It is used to configure parameters that are then accessed from the Functions code. See https://firebase.google.com/docs/functions/config-env

fwiw
Firebase Environment variables docs

Keep in mind that only lowercase characters are accepted in keys; uppercase characters are not allowed.

A bit odd that uppercase isn't allowed, I'm sure there is a good reason for it.
