Apigee emulator: getting "plain HTTP request was s... - Page 2

Hi! I'm trying to use TargetServers to decouple concrete endpoint URLs from TargetEndpoint configurations, as specified here: https://cloud.google.com/apigee/docs/api-platform/deploy/load-balancing-across-backend-servers .

When developing locally using VSCode plugin, I'm getting "plain HTTP request was sent to HTTPS port" when trying to hit HTTPS backends.

This is working fine when deploying to apigee.google.com. However, when developing locally using VSCode plugin, I'm getting "plain HTTP request was sent to HTTPS port" when trying to hit HTTPS backends.

Apigee emulator runtime version: 1.6.1.

Restarting/resetting the emulator doesn't help.

apiproxies/sample-v1/apiproxy/targets/default.xml:

<TargetEndpoint name="default">
    <HTTPTargetConnection>
        <LoadBalancer>
            <Server name="sample-backend"/>
        </LoadBalancer>
    </HTTPTargetConnection>
</TargetEndpoint>

environments\local\targetservers.json:

[{
  "name": "sample-backend",
  "host": "httpbin.org",
  "port": 443,
  "sSLInfo": {
    "enabled": "true"
  }
}]

When issuing this command:

curl -v http://127.0.0.1:8998/sample/v1/get

I'm getting the following response:
