REST API returning an AUTHORIZATION_ERROR - rest

Question

Following some of the examples provided in the Invoicing REST API https://developer.paypal.com/docs/api/#invoicing I am always receiving an AUTHORIZATION_ERROR.
Here is an example:
First retrieving my token:
curl https://api.sandbox.paypal.com/v1/oauth2/token \
> -H "Accept: application/json" \
> -H "Accept-Language: en_US" \
> -u "AbNzCxxxxs6iVF0:EBhQWxxxxxxrgefvhb" \
> -d "grant_type=client_credentials"
{"scope":"openid https://uri.paypal.com/services/invoicing https://api.paypal.com/v1/payments/.* https://api.paypal.com/v1/vault/credit-card/.* https://api.paypal.com/v1/vault/credit-card","access_token":"F9Ig.4FXq1DQICPrMaUUb0-K--3dWBHvqRck636df4A","token_type":"Bearer","app_id":"APP-80W284485P519543T","expires_in":28800}%
Then using that token to create an invoice:
curl -v -X 'POST' 'https://api.sandbox.paypal.com/v1/invoicing/invoices' \
> -H 'Content-Type: application/json' \
> -H 'Authorization: Bearer F9Ig.4FXq1DQICPrMaUUb0-K--3dWBHvqRck636df4A' \
> -d '{

I can successfully send a payment request as is done here: https://developer.paypal.com/docs/integration/direct/make-your-first-call/
But for some reason the Invoice does NOT work.
I have verified that in my sandbox app I have enabled invoicing
Any help appreciated, thanks in advance.

Please change the email address(rdg#rapiddg.com) to the one that linked to the app you created before.
Please go ahead to check the email address in your REST APP.
