Error Unauthorized: 401 while starting the application

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!

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.
