Next.js镜像部署AKS遇exec格式错误，架构匹配仍未解决

我为Next.js应用制作了自定义Docker镜像并推送到Azure容器注册表（ACR），部署到Azure Kubernetes服务（AKS）集群的Pod后，Pod状态显示为CrashLoopBackOff，Pod日志报错：

exec /usr/local/bin/docker-entrypoint.sh: exec format error

此前曾因构建镜像的架构与AKS节点（Linux/AMD64）不匹配（本地为ARM架构）出现该问题，但切换到amd64架构构建后，错误依旧。已确认当前镜像和节点架构均为amd64：

• 使用命令docker buildx build --platform linux/amd64 -t <container_url>/<container_image>:<tag> . --load构建amd64镜像
• 用docker push <container_url>/<container_image>:<tag>推送到ACR
• 本地运行docker run --platform linux/amd64 -it --rm <acr_name>.azurecr.io/<image_name>:v0.1.0验证镜像正常启动
• 通过docker image inspect <image_id>确认镜像架构为amd64，kubectl get nodes -o=jsonpath='{.items[0].status.nodeInfo.architecture}'确认节点架构为amd64

我还尝试在Dockerfile开头添加shebang，且设置了ENTRYPOINT []，但镜像历史仍显示/bin/sh -c #(nop) ENTRYPOINT ["docker-entrypoint.sh"]。

我的Next.js应用是通过npx create-next-app@latest生成的，未做代码修改。

请问如何解决该错误？或有哪些进一步诊断的方法？另外，若有近年关于将Next.js容器化并部署到AKS的深度教程也请推荐，谢谢！
