部署在AKS容器中的Probot GitHub应用无法接收Webhook求助

我使用Probot开发了一个GitHub应用，通过smee.io在本地测试成功。随后将其打包为Docker镜像推送到ACR（Azure容器注册表），并部署到Azure Kubernetes Service(AKS)集群中，同时配置了Ingress路由Webhook，但始终出现404错误。

我的Dockerfile #

参考示例构建的Dockerfile如下：

FROM my-image-registry/node:18-alpine3.16 as build

# set working directory 
WORKDIR /app/probot/

ENV PATH /app/node_modules/.bin:$PATH

# install and cache app dependencies

COPY ./.npmrc ./
COPY ./package.json ./
# COPY ./tsconfig.json ./

RUN npm cache clean --force && npm install --force --loglevel verbose

FROM my-image-registry/node:18-alpine3.16 as app

WORKDIR /app/probot/

COPY --from=build /app/probot/node_modules ./node_modules
COPY . ./

RUN npm run build

EXPOSE 3005

COPY .env ./

#CMD npm run start
CMD [ "npm", "start" ]

Kubernetes部署配置 #

通过kubectl部署到Kubernetes后Pod已成功运行，配置如下：

---
kind: Deployment
apiVersion: apps/v1
metadata:
  labels:
    app: probot-service
  name: my-app-pod
  namespace: my-namespace
spec:
  replicas: 1
  selector:
    matchLabels:
      app: probot-service
  template:
    metadata:
      labels:
        app: probot-service
    spec:
      containers:
        - name: probot-service
          image: myacrurl/my-app-docker-image:d1.0
          imagePullPolicy: Always
          ports:
            - containerPort: 3005
      nodeSelector:
        agentpool: apppool

---
apiVersion: v1
kind: Service
metadata:
  labels:
    app: probot-service
  name: probot-service
  namespace: my-namespace
spec:
  ports:
    - name: http
      port: 80
      targetPort: 3005
    - name: https
      protocol: TCP
      port: 443
      targetPort: 3005
  selector:
    app: probot-service
  type: ClusterIP

Pod日志信息 #

执行kubectl logs <podname> -n <namespace>查看日志，显示：

INFO (server): Running Probot v13.0.2 (Node.js: v18.8.0)
INFO (server): Listening on http://localhost:3005

Ingress路由配置 #

配置的Ingress用于将Webhook路由到容器，内容如下：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: probot-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/rewrite-target: /$2
    nginx.ingress.kubernetes.io/use-regex: 'true'
spec:
  rules:
  - host: probot.mydomain.com
    http:
      paths:
      - pathType: Prefix
        path: /probot(/|$)(.*)
        backend:
          service:
            name: probot-service
            port:
              number: 80

我尝试过硬编码应用ID、Webhook密钥、安装ID等必要参数，也尝试过通过环境变量配置，以及在构建镜像时复制.env文件，但都无法解决问题。请问我哪里操作有误？Probot应用是否可以部署在AKS上？
