Deploying Go app on Google Cloud 'missing go.sum entry'

I'm trying to deploy a simple API on Google Cloud using Go 1.19

> go version
go version go1.19.2 windows/amd64

I'm following this documentation as a template to deploy my app. But the deploy fails.

Updating service [default]...failed.

Running the suggested go mod download github.com/onsi/ginkgo does not solve anything.
Also tried go mod tidy as suggested in another posts but same results. Also tried with vendor folder, but nothing again.

This is my app.yaml

runtime: go116

go.mod

EDIT 1: Already tried to change runtime: go and to runtime: go119 but those are not supported and return "invalid go runtime".

To anyone who might have this problem, I just deployed the app on Cloud Run instead of App Engine and everything runs smoothly. I was not able to deploy it on App Engine and i think that the only way to do so is adapting the code and modules to the latest runtime version available for GCP (currently Go 1.16).
