Getting error in Step 4. (Curl) Invalid OAuth about messenger-bot-tutorial HOT 8 OPEN

The problem is with the curl's syntax.
Instead of (<> vs {})
curl -X POST "https://graph.facebook.com/v2.7/me/subscribed_apps?access_token="
use
curl -X POST "https://graph.facebook.com/v2.7/me/subscribed_apps?access_token={token}"

The v2.7 or v2.6 makes no difference - it works with both.

Hope it helps.

Same here anyone found the problem?

Update: I seemed to have gotten around it with trial and error here is what I did.

First make sure you type =page_access_token not =<page_access_token>
I also added a namespace and app domain and website URL in the basic setting section of the app.

I'm not certain which of these solved the problem but I'd guess at dropping the <> syntax.

Hope that helps.

In v2.8 you should use only this:
curl -X POST "https://graph.facebook.com/v2.7/me/subscribed_apps?access_token="

from messenger-bot-tutorial.

just get rid of those angle brackets around the token...and you will be just fine
for example

curl -X POST "https://graph.facebook.com/v2.6/me/subscribed_apps?access_token=EAAJ22uv7dO8BAEwvZApIIfLyhmgRjE00a3XHiZAnm3ZBqfzJkMX4GoCjnXCbI5IOBINLP5443v8szAYcvcQSbZB8B2WAbxMGIX5mU"

I have had this issue as well and solved it but now there is another typer of error : 2500. The message is "An active access token must be used to query information about the current user". I am confused, any help ?
