generator-jhipster: Unable to login using oAuth2/OKTA with docker-compose prod package - Error 'User could not be found'

Overview of the issue

Login doesn’t work with oAuth2/Okta using docker-compose: Error 500 - ‘User could not be found’. But, login works well when using keycloak instead of OKTA. The error occurred only with prod profile and docker-compose.

Motivation for or Use Case

Reproduce the error

• Generate o Monolith app with oAuth2 option
• Change OpenID Connect Settings to use OKTA instead of Keycloak: src/main/docker/app.yml and src/main/resources/application.yml
• build docker image using ‘./mvnw verify -Pprod dockerfile:build -DskipTests’
• Start app using ‘docker-compose -f src/main/docker/app.yml up -d’
