RDP api.refinitiv.com/auth/oauth2/v1/token scope error

I am using RDP API to get data from resource https://api.refinitiv.com/data/funds/v1/assets

In the rquest, a Bearer type token obtained from https://api.refinitiv.com/auth/oauth2/v1/token is being sent.

The problem is that I am getting the following error:

### Request
POST https://api.refinitiv.com/data/funds/v1/assets
Authorization: Bearer XXXXXXXXXXXXXXXXXXX

{"properties": [{"name": "prices"},{"name": "CumulativeCalcs"},{"name": "RollingPerformance"}], "universe":{"symbols": ["LP68092650","LP68092651"]}}


### Response
{
  "error": {
    "id": "5aff0b0e-fc14-40ab-8357-b424ea44b73c",
    "code": "insufficient_scope",
    "message": "access denied. Scopes required to access the resource: [trapi.data.funds.assets.read] or [trapi.demo-access]. Missing scopes: [trapi.data.funds.assets.read trapi.demo-access]",
    "status": "Forbidden"
  }
}

I have tried to generate the token in the following ways, obtaining the same error in both cases

### REQUEST A ###
POST https://api.refinitiv.com/auth/oauth2/v1/token
Content-Type: application/x-www-form-urlencoded

client_id=XXXXXXXXXXX
&scope=trapi
&password=XXXXXXXXXXX
&grant_type=password
&takeExclusiveSignOnControl=true
&username=XXXXXXXXXXX

--------------------------

### REQUEST B ###
POST https://api.refinitiv.com/auth/oauth2/v1/token
Content-Type: application/x-www-form-urlencoded

client_id=XXXXXXXXXXX
&scope=trapi.data.funds.assets.read
&password=XXXXXXXXXXX
&grant_type=password
&takeExclusiveSignOnControl=true
&username=XXXXXXXXXXX

It should be noted that the service responded correctly in recent days through REQUEST A

What could be the problem?
