Universal Print (UP) Printer Registration Invalid Invalid Token, The Audient Invalid

[hungnq39]

According to the document Printer Registration , I obtained the Access Token in step 1.2.1.3.2.2 Retrieving the user token.
This token can be used in the required authorization header (described in section 1.2.1.1.2) when sending a request to register a printer with Universal Print.
But when I send the request to api https://register.print.microsoft.com/api/v1.0/register
, an error code returned as 401 Unauthorized with description Bearer error = "invalid_token", error_description = "The audience is invalid"
Let me know what to do?

@hungnq39, please message me directly.  There are a few things to discuss through which are difficult to do in this format.

Thanks,
