firebase-tools: Function deployment fails when running on Node 15.8.0

[REQUIRED] Environment info

firebase-tools: 9.3.0 Node Version: 15.8.0 Platform: Linux 5.4.89-1-MANJARO

[REQUIRED] Test case

Deploy the function generated initially when you run firebase init and select functions.

// index.js
const functions = require("firebase-functions");
exports.helloWorld = functions.https.onRequest((request, response) => {
	functions.logger.info("Hello logs!", {structuredData: true});
	response.send("Hello from Firebase!");
});

[REQUIRED] Steps to reproduce

Deploy the function above:

$ firebase deploy --only "functions:helloWorld"

[REQUIRED] Expected behavior

Expected behavior is to deploy the function(s) without any errors.

[REQUIRED] Actual behavior

Deployments fails with the following output message in local terminal:

$ firebase deploy --only "functions:helloWorld"

=== Deploying to 'test-functions-d4276'...

Functions deploy had errors with the following functions:
        helloWorld


To try redeploying those functions, run:
    firebase deploy --only "functions:helloWorld"


To continue deploying other features (such as database), run:
    firebase deploy --except functions

Error: Functions did not deploy properly.

Workaround

I switched to Node version 14.x.x and everything worked fine. This may be a duplicate of #3108. The SO link they provided also has more details so it might be worth looking into. In #3108 they seem to have trouble deploying with node versions aside from 15.x.x. They mention that deploy requires keyboard input in GCP; in my logs this does show up but seems selects an input automatically anyway, the selected input being [N]one. I am listing the summary for this particular log message below. Note, this happens before the error message I attached farther up the document.
