Error Unauthorized: 401 while starting the application

Start with the application.yml and helm-chart/dev.values.yaml examples, then compare how the Spring Cloud Config client handles the username property and SPRING_CLOUD_CONFIG_USERNAME across the reported versions. Confirm whether the application.yml setting should work in Spring Cloud 2022.0.4 and document the required configuration or the regression, including behavior for both deployed environments.

Hi Spring Cloud team,

I am going to upgrade Spring cloud from 2022.0.2 to 2022.0.4. And I got an issue while starting my application.

Spring boot: v3.1.1
Spring cloud: v2022.0.4

In application.yml:

spring.cloud.config:
  enabled: true
  username: config-service
  password: test-password

In helm-chart/dev.values.yaml:

namespace: dev

replicaCount: 1

springProfile: dev

env:
  - name: SPRING_CLOUD_CONFIG_ENABLED
    value: 'true'
  - name: SPRING_CONFIG_IMPORT
    value: configserver:http://config-service

secretEnv:
  - name: SPRING_CLOUD_CONFIG_PASSWORD
    secretKeyRefName: spring-cloud-config-password
    secretKeyRefKey: spring-cloud-config-password

Here is the error log:

It looks like the application couldn't get username in application.yml.
I was trying to set it as an environment variable SPRING_CLOUD_CONFIG_USERNAME in helm-chart/dev.values.yml, and it starts successfully.

  - name: SPRING_CLOUD_CONFIG_USERNAME
    value: config-service

Could you please help to check this case? In new Spring cloud version, do we have to set SPRING_CLOUD_CONFIG_USERNAME as an environment variable on each deployed environment? For example, I have 2 environments of dev and prod

Thanks for your help!
