AWS Lambda，調用 PutObject 操作時發生錯誤 (InvalidToken)：提供的令牌格式錯誤或無效

Question

我制作了一個 Django 應用程序並嘗試使用 Zappa 和 AWS Lambda 對其進行部署。

我的部署已成功部署，但圖像未上傳到 AWS S3 以調用 API。

這是我的 cloudwatch 錯誤日志

所有訪問密鑰都已正確驗證並在本地環境中正常工作。 我該如何解決這個問題？

我的設置.py

AWS_ACCESS_KEY_ID = env("AWS_S3_ACCESS_KEY_ID")
AWS_SECRET_ACCESS_KEY = env("AWS_S3_SECRET_ACCESS_KEY")
AWS_S3_REGION_NAME = "ap-northeast-2"
AWS_STORAGE_BUCKET_NAME = env("AWS_STORAGE_BUCKET_NAME")
AWS_S3_CUSTOM_DOMAIN = (
    f"{AWS_STORAGE_BUCKET_NAME}.s3.{AWS_S3_REGION_NAME}.amazonaws.com"
)
AWS_DEFAULT_ACL = "public-read"
