PERMISSION_DENIED: The caller does not have permission

Hy there! How are you?

I’m developing a Google Cloud Function and it is great! But since last week I’m getting an issue testing locally with functions-framework-nodejs

Unhandled rejection

It occurs at the end of the execution of the function.

Any clue of what it is?

Version: “@google-cloud/functions-framework”: “^1.6.0”

Thanks!

I tried to isolate some parts of the code and it seems to be LogginWinston it’s causing the error, when i comment the “loggingWinston” on the creation of the logger, it works just fine. I dont know if there’s a relation with the function framework.

Thanks!

code:

/** libraries */
const winston = require('winston')
const { LoggingWinston } = require('@google-cloud/logging-winston')

const loggingWinston = new LoggingWinston()

// Create a Winston logger that streams to Stackdriver Logging
// Logs will be written to: "projects/YOUR_PROJECT_ID/logs/winston_log"
const logger = winston.createLogger({
  level: 'info',
  transports: [
    new winston.transports.Console({
      level: 'debug',
      format: winston.format.combine(
        winston.format.colorize(),
        winston.format.simple()
      )
    }),
    // Add Stackdriver Logging
    loggingWinston
  ]
})

exports.execute = async (_request, response) => {
  logger.info('START')
  response.status(200).end()
}

Hi there! I think i found out the problem, it’s not really a problem, but sure it seems to in the @google-cloud/logging-winston.

It was missing a permission for the Logging API on the service account. I think just the message it wasn’t much clear.

But the code is right here:

https://github.com/denisdnc/cloud-functions-example

Set a service account credentials path:

export GOOGLE_APPLICATION_CREDENTIALS="/home/user/credential.json"

And start the app:

npx @google-cloud/functions-framework --target=execute

Do the request on http://localhost:8080/

Then should log the problem above.

Thank you guys for the support!
