Serverless deploy to LocalStack fails: “Invalid character in header content [authorization]”

Running serverless deploy --stage local against LocalStack aborts during the “Resolving AWS account ID” step with the error:

Unable to find function cleanup on plugin Esbuild

Versions

使用 serverless.ts 和 docker-compose.yml 重现 serverless deploy --stage local，重点关注“Resolving AWS account ID”步骤和 authorization-header 错误。检查所列出的 Serverless Framework、serverless-localstack、LocalStack 和 Node.js 版本。完成的标准是部署过程越过账户解析，继续进行 packaging 和 CloudFormation synthesis，且不再出现 invalid-header 失败。
