Why Authorization error occurred with a valid token?

Question

Django

I tried to make an invoice through PayPal-Python-SDK, but I got an Authorization error occurred error, now I'm trying to do the same through curl.

curl -v https://api.sandbox.paypal.com/v1/oauth2/token \
   -H "Accept: application/json" \
   -H "Accept-Language: en_US" \
   -u "client_id:client_secret" \
   -d "grant_type=client_credentials"

I get an answer

I take my token and try to make an invoice

curl -v -X POST https://api.sandbox.paypal.com/v1/invoicing/invoices/ \
-H "Content-Type: application/json" \
-H "Authorization: Bearer ТУТ МОЙ ТОКЕН" \

}'

And I still get the error

{"name":"AUTHORIZATION_ERROR","message":"Authorization error occurred.","information_link":"https://developer.paypal.com/docs/api/invoicing/#errors","debug_id":"c26d163a87c8d"}

Who came across, tell me, pliz, what's wrong, otherwise I'm already sick of banging my head against the wall (
