Error invoking firebase function referencing local configuration variables from Firebase Functions Shell

This is a continuation of troubleshooting this problem and a separate issue related to implementing a suggested solution.

I am attempting to consume Firebase function configuration from a locally-served environment as outlined here but I get an unexpected error.

  1. I create a ".runtimeconfig.json" file within my functions directory containing this:

{ "auth": { "clientid": MY_CLIENT_ID, "signoutreturnto": SOME_URL, "responsetype": SOME_URL, "redirecturi": SOME_OTHER_URL, "scope": SOME_OTHER_STRING, "domain": SOME_DOMAIN } }

  1. I execute the following commands from the firebase CLI (within the functions directory):

    • firebase functions:config:get > .runtimeconfig.json
    • firebase experimental:functions:shell

  2. I execute my config function via the cli:

    config()

  3. I get the following error output in the console:

config()

TypeError: config is not a function

my other functions, bigben & firebaseConfig execute as expected from the CLI

Solution

  • If you want to see your functions config at the the CLI emulator prompt, you should run the emulator command from your functions directory:

    $ cd functions
$ firebase experimental:functions:shell

    Then, at the firebase prompt, you can access your config like this:

    firebase> const functions = require('firebase-functions')
firebase> functions.config()

    That should print your config. Normally you don't need to do something like this - you would instead just read the config from inside the emulated function using functions.config().
