Azure部署Docker镜像版Python函数应用无函数显示且404问题求助

我通过代码直接部署HTTP触发函数到Azure后，函数能正常显示并返回数据。但打包成Docker镜像后，本地运行正常，部署到Azure却看不到函数，调用时返回404错误。已对比两个函数应用的环境变量，完全一致。查了两天博客仍没解决，附上相关文件和日志，求帮忙排查。

Dockerfile #

# Base image with Python 3.9

# Set environment variables to avoid writing .pyc files and buffering output
ENV AzureWebJobsScriptRoot=/home/site/wwwroot \
    AzureFunctionsJobHost__Logging__Console__IsEnabled=true

# Install git to clone the Bitbucket repository
RUN apt-get update && apt-get install -y git 


 ENV AZURE_FUNCTIONS_ENVIRONMENT=Development

#Copy secrets file
RUN mkdir /etc/secrets/
ENV FUNCTIONS_SECRETS_PATH=/etc/secrets
ENV AzureWebJobsSecretStorageType=Files
