Google analytics API with a service account wrongfully Quota Error

tl;dr: I'm getting Quota Error: You have exceeded the maximum number of writes/day for this project even tho I have 50k queries / day as the quota limit.

I have a project on google cloud consle with GA API enabled:

Oddly enough, in the GA Quotas view I see two anonymous Query sections, both with 50k queries / day: (deleted the graphs to capture both quotas on same screen)

A side question here, why do I have two Query sections? what does each mean?

I have a service account with access to this project:

with a generated JSON key:

and I'm using that service account to make API requests:

const path = require('path')
const { google } = require('googleapis')

module.exports = createApiInstance

const keyFilePath = path.resolve(__dirname, '../../credentials.json')

const auth = new google.auth.GoogleAuth({
  keyFile: keyFilePath,
  scopes: ['https://www.googleapis.com/auth/analytics.edit'],
})

auth.getClient().then(client => {
  client.request(params)
})

I can get away with just a few requests in a day before I run into the quota limit error.

One weird thing is that even tho I just made some requests a few minutes ago, the service account's logs come up empty:

Which would be tempting to say the service account isn't being used, but, if that was the case how would I be able to get away with the few requests that do actually pass?

I'm not using any Auth'ing other than the service account generated credentials file ‍♀️

As an aside, we are using the same service account with the same credentials file on another project for a different google API, and it works as expected.

any ideas what's going on here?
