I'm trying to log to help to debug my code using console.log() on Google Actions using webhook. But I can't find it anywhere. Where is stored the output console.log()?
console.log('')
I tried to find in Stackdriver log, but couldn't find it.
It is stored in Stackdriver if you're using Cloud Functions on Google Cloud or Firebase. Make sure that you adjust the filter to logs from Cloud Function
If you're not using Google Cloud for hosting your webhook, you'll need to check your hosting provider.
