I am trying to run the command node createTable.js $DB_USER $DB_PW $DB_NAME $CLOUD_SQL_CONNECTION_NAME from windows power shell as it is indicated in the Google cloud Platform nodejs samples for connecting to cloudsql from cloudrun using knex in this repository.

I have intalled and Started the Cloud SQL Proxy and followed all the instructions including adding service accounts in the sample. But each time I run the createTable.js script from power Shell, I get the following errors in Powershell:

I followed the documentation on pub/sub notifications with the push method here

And I want to have authentication on my call with JWT. I looked at their GitHub example here
