Unable to subscribe the App to the Page

问题:

I'm following the getting started tutorial(https://developers.facebook.com/docs/messenger-platform/quickstart) and this tutorial(https://github.com/jw84/messenger-bot-tutorial) to create a simple bot for messenger. I have created a fb page and an app. I've got one Heroku server running and have successfully done the webhook setup. I've also generated the page access token.

Now when I try to subscribe the App to the Page using:

curl -ik -X POST "https://graph.facebook.com/v2.6/me/subscribed_apps?access_token=<my_access_token>"

I get the following error:

Invoke-WebRequest : A parameter cannot be found that matches parameter name 'ik'.
At line:1 char:6
+ curl -ik -X POST "https://graph.facebook.com/v2.6/me/subscribed_apps?access_toke ...
+      ~~~
+ CategoryInfo          : InvalidArgument: (:) [Invoke-WebRequest], ParameterBindingException
+ FullyQualifiedErrorId : NamedParameterNotFound,Microsoft.PowerShell.Commands.InvokeWebRequestCommand

when I run without the -ik -X :

curl "https://graph.facebook.com/v2.6/me/subscribed_apps?access_token=<my_access_token>"

i get:

How can I fix the above error?
