Hello Yezzer, If you think this is caused by errors on the GCP side, you are encouraged to rather open an issue in the Public Issue Tracker <https://issuetracker.google.com/>, as more details are needed to investigate, some of which are of a private nature. A publicly visible thread like this one is not suitable for such an investigation.
There is a community tutorial <https://cloud.google.com/community/tutorials/mongodb-atlas-appengineflex-nodejs-app> "Hello World app - MongoDB Atlas and App Engine flexible environment with Node.js" that may serve as a good example. It is worthwhile going through it and verifying that you have set all details correctly.
