2.0.1-beta.28 fails to start host with proxy on MacOS

[JohnReeson]

Issue is from SO.

CLI installed on MacOS using brew has such trouble. While on windows, things works.

The sample to repro includes two files below and one host.json file with only {}.
proxies.json

{
    "$schema": "http://json.schemastore.org/proxies",
    "proxies": {
        "HelloWorldProxy": {
            "matchCondition": {
                "route": "api/hello/{name}"
            },
            "responseOverrides": {
                "response.statusCode": "200",
                "response.statusReason": "OK",
                "response.headers.Content-Type": "application/json",
                "response.body":{
                    "message":"Hello, {name}"
                }
            }
        }
    }
}

local.settings.json

{
  "IsEncrypted": false,
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "dotnet",
    "AzureWebJobsStorage": "UseDevelopmentStorage=true"
  }
}

[02/06/2018 17:10:59] Stopping Host

[maciejgos]

I execute func start as superuser and it works. So issue is related to macOS. Problem is only related to proxies functionality.

[JohnReeson]

Another simple question: Have seen that cli(both v1&v2) output uri with proxy name like http://localhost:7071/api/HelloWorldProxy instead of the route like http://localhost:7071/api/hello/{name}, is it by design?

[JohnReeson]

@safihamid Could you have a look at this issue? Thanks.

[safihamid]

Yes we’ll be looking at this.

[safihamid]

@vfedonkin would you please look into this? thanks

[vfedonkin]

Looking

[ChristianWeyer]

I have the same issue with 2.0.1-beta.29 @vfedonkin

[ChristianWeyer]

Do you have any idea what could be wrong @vfedonkin or @safihamid ? This blocks me/us (and running elevated with sudo is not really an option ;-) )
Thanks!

[safihamid]

@ChristianWeyer yes we have identified the bug and the fix will be released within the next few weeks.

[ChristianWeyer]

Thank you! Is there any workaround right now other than 'sudo'? @safihamid ?

[alexkarcher-msft]

@ChristianWeyer , if you make a folder in your /users foder called "[username]\LogFiles\Application\Proxies\DetailedTrace" that should allow the proxies to run successfully.
