LinkedIn API not providing the user URN

How To
,
1

am trying to use linkedin API to make users share content from our platform to their profiles in LinkedIn, in the Documentation the API requires a user URN in the request body.
But when i follow how to get it i see a legacy APIs shares/userId that seems do not work anymore ( They don’t even provide an id to test the legacy API in the response)

I have this scopes
email, openid, profile, r_ads, r_events, r_learningdata, r_liteprofile, r_marketing_leadgen_automation, w_member_social

I saw many people having the same problem but there is no response on the issue or any clarification

Endpoints a tried

  1. https://api.linkedin.com/v2/userinfo


    Response:
{
	"sub": "XXX-XXXX",
	"email_verified": true,
	"name": "XXXX XXXXX",
	"locale": {
		"country": "FR",
		"language": "fr"
	},
	"given_name": "XXXX",
	"family_name": "XXXX",
	"email": "XXXXXX@gmail.com",
	"picture": "XXXXXXX"
}
  1. https://api.linkedin.com/v2/me


    Response:.
{
	"localizedLastName": "XXXX",
	"profilePicture": {
		"displayImage": "XXXXX"
	},
	"firstName": {
		"localized": {
			"fr_FR": "XXXX"
		},
		"preferredLocale": {
			"country": "FR",
			"language": "fr"
		}
	},
	"lastName": {
		"localized": {
			"fr_FR": "XXXX"
		},
		"preferredLocale": {
			"country": "FR",
			"language": "fr"
		}
	},
	"id": "XXX-XXXX",
	"localizedFirstName": "XXXX"
}

No user URN returned in both

In the response of the second endpoint, “id”: “XXX-XXXX” is the major part of URN as URN is : urn:li:person:XXX-XXXX
