Log message if branch doesn't exist

Hi,

We are using spring-cloud-config-server with on one side, a Git repo, and on another side, Vault. We migrated our codebase from an on premise Gitlab to Github. Below, you will find our application configuration :

application.yml

server:
  servlet:
    contextPath: /configuration-server
  port: 8888
spring:
  cloud:
    config:
      server:
        vault:
          order: 1
          host: ${VAULT_HOST}
          port: ${VAULT_PORT}
          kv-version: ${VAULT_KV_VERSION}
          scheme: ${VAULT_SCHEME}
          backend: ${VAULT_BACKEND}
          profileSeparator: /
        git:
          order: 2
          uri: ${GIT_URI}
          search-paths: '{application}'
          default-label: ${DEFAULT_BRANCH:master}
          proxy:
            http:
              host: ${HTTP_PROXY_HOST:localhost}
              port: ${HTTP_PROXY_PORT:3128}
              non-proxy-hosts: ${HTTP_NON_PROXY_HOSTS:}
          strict-host-key-checking: true
          ignore-local-ssh-settings: true
          private-key: ${GIT_ACCESS_PRIVATE_KEY:changeit}
          passphrase: ${GIT_ACCESS_PASSPHRASE:changeit}
          host-key: ${GIT_ACCESS_HOST_KEY:changeit}
          host-key-algorithm: ${GIT_ACCESS_HOST_KEY_ALGORITHM:ssh-rsa}

  profiles:
    active: git, vault

~/.ssh/known_hosts

github.com <key of github>

We are facing a really weird issue. In fact, services that want to get their config do not get any answers from the config-server.

... same message over and over

However, the git repo is well cloned in /tmp.

The issue is produced from amazon containers managed with Rancher and that used a proxy.

Any idea ?

Regards.

Start at the configuration-server request path shown in the logs and inspect the repeated GitCredentialsProviderFactory activity. Reproduce the Git backend request with a branch that does not exist, comparing it with the repository successfully cloned in /tmp. Done means the missing-branch condition produces a clear log message.
