Apigee : Unexpected EOF at target error when configuring TargetEndpoint with Port 443

Issue: Unexpected EOF at target error when configuring TargetEndpoint with port 443

Description:
I'm encountering an error consistently when configuring a TargetEndpoint with Port 443 in Apigee. Here's the configuration I'm using:

src/main/apigee/apiproxies/ECHO-proxy/apiproxy/proxies/default.xml

<ProxyEndpoint name="default">
  <HTTPProxyConnection>
    <BasePath>/test</BasePath>
  </HTTPProxyConnection>
  <RouteRule name="backend">
    <TargetEndpoint>backend</TargetEndpoint>
  </RouteRule>
</ProxyEndpoint>

src/main/apigee/apiproxies/ECHO-proxy/apiproxy/targets/backend.xml

<TargetEndpoint name="backend">
  <HTTPTargetConnection>
    <Properties/>
    <LoadBalancer>
      <Server name="google"/>
    </LoadBalancer>
    <Path>/echo</Path>
  </HTTPTargetConnection>
</TargetEndpoint>

The backend TargetEndpoint is configured to use a load-balancer targeting a server named google. However, whenever I attempt to utilize this configuration, I receive the following error:

{
  "fault": {
    "faultstring": "Unexpected EOF at target",
    "detail": {
      "errorcode": "messaging.adaptors.http.flow.UnexpectedEOFAtTarget",
      "reason": "TARGET_READ_UNEXPECTED_EOF"
    }
  }
}

Environment:

• VS Code Version: 1.89.1
• Cloud Code Version: 2.10.0

Steps to Reproduce:

1. Configure a ProxyEndpoint with the provided configuration.
2. Configure a TargetEndpoint using the provided configuration.
3. Attempt to use the ProxyEndpoint.
4. Observe the error described above.

Expected Behavior:
The ProxyEndpoint should route requests to the TargetEndpoint without encountering the EOF error.

Additional Information:
I'm currently using VS Code version 1.89.1 and Cloud Code version 2.10.0. This issue persists across multiple attempts and configurations.

The targetservers.json configuration is as follows:

[
  {
    "enabled": true,
    "name": "google",
    "description": "google",
    "host": "mocktarget.apigee.net",
    "port": 443
  }
]

i am able to get the expected response if i am use the same target endpoint as port 80
Please let me know if there's any additional information needed to resolve this issue.
