求助：GoLang应用无法更新部署至Google AppEngine

部署Go项目到Google App Engine时突然失败，日志输出错误如下：

排查情况 #

• 最初猜测Go 1.11已停用，但切换至Go 1.19后问题仍未解决
• 测试发现使用新服务名称可正常部署，但更新现有服务（即使修改服务版本号）时会失败
• 已在两个Go项目（其中一个未做任何修改）上验证该问题，Java项目可正常部署

部署命令 #

gcloud app deploy --project=staticform --version=1 app.yaml

更新补充：app.yaml配置 #

runtime: go111
automatic_scaling:
  min_idle_instances: 0
  max_instances: 1

handlers:
  - url: /.*
    script: auto
    secure: always
  - url: /admin/.*
    script: auto
    secure: always
    login: admin
