[REQUIRED] Version info

firebase-admin 12.1.1 firebase-functions 5.0.1 node v20.5.1

[REQUIRED] Test case

It appears that in the past 48 hours warnings from firebase-functions/logger have been showing up as errors.

Deploy this http function and load it:

import { onRequest } from 'firebase-functions/v2/https'
import {
  info,
  debug,
  warn,
  error,
} from 'firebase-functions/logger'

export const testLogging = onRequest(
  {
    region: 'australia-southeast1',
  },
  async (req, res) => {
    debug('Testing debug log level')
    info('Testing info log level')
    warn('Testing warn log level')
    error('Testing error log level')

    res.status(200).send('🪵')
  }
)

Then view Google Logs Explorer and look for the warn log level message:
