[REQUIRED] Test case

export const doSomething = functions.https.onCall(async (data, context) => {

  console.log('hello world');

});

[REQUIRED] Steps to reproduce

1. Deploy a callable function with a console.log()
2. Trigger function
3. Go to Functions > Logs in the Firebase console

[REQUIRED] Expected behavior

It should log the different types of severity and be sortable in the firebase console

[REQUIRED] Actual behavior

Not logging any logs with a severity of 'INFO' when console.log() is used

Were you able to successfully deploy your functions?

Yes

Are you certain your function is getting triggered? onCall functions do some request validation and authentication before triggering the user codepath, my best guess is that the request isn't actually making it to your code in the first place.

Additionally, you might want to look into using the new logging SDK (see release notes) for Node 10.

No it's making the request and everything operates as usual it's just all of my logging is messed up in my Firebase console. Here's an example of an error response from Stripe being emitted with console.log().

It's separating every property to it's own line. Not sure why and I'm not able to sort by log level 'INFO' because none of this is given that log level even though it's being emitted with console.log

[mbleigh]

In that case the new logging API is definitely what you want instead. Try upgrading firebase-functions to 3.7.0 and using:

functions.logger.log('hello world')

and see if you're still experiencing similar issues.

@mbleigh Right so I did that and when I use functions.logger.log() I get a type error:

Property 'logger' does not exist on type 'typeof import("...functions/node_modules/firebase-functions/lib/index")'.ts

[mbleigh]

Are you certain you're on the latest SDK? The release was just yesterday:

npm i --save firebase-functions@^3.7.0

[kyleabens]

Yep I just double checked to confirm. Could the way I'm importing it have anything to do with it? I use typescript.

import * as functions from 'firebase-functions';

functions.logger.log('hello world')

Ugh all I had to do was restart VS Code. Sorry about that!
