Hi @Robinwilliam15 ,

Welcome to the Google Cloud Community!

Try to perform the following troubleshooting options:

1. You need to add tags before you can use them in your app.yaml file. See documentation here
2. Check your CPU in resources. For the number of cores, it should be one, an even number between 2 and 32, or a multiple of 4 between 32 and 80. See documentation here.
3. Check your configuration, especially with the VPC network configuration.
4. Check your app.yaml configuration file. Starting with Node.js version 18, you must specify the version of the operating system. Read more about app.yaml configuration in this documentation.
5. Check if line 22 should be indented under beta_settings.
6. You can also get in touch with Google Cloud Support if the above options don't work.

let me know if it helped, thanks!
