The error seems specific to the Spring Boot, rather than App Engine. Can you confirm this setup works appropriately before deploying to App Engine? Similar errors were reported on Springboot applications on these Stackoverflow links[1][2]
Anyway, I think it would be more appropriate to report this type of Code-related issue on Stackoverflow where Spring Boot developers and some of our GCP Support Engineers could help. The groups thread are specifically for GCP product related issues, rather than Code related issues.
