The creatives endpoint of the new versioned Linkedin API throws RESOURCE_NOT_FOUND error

Question

We are trying to move to using the new versioned Linkedin API. (https://learn.microsoft.com/en-us/linkedin/marketing/versioning?view=li-lms-unversioned) With our implementation to accommodate the changes the rest of the new API calls work, but non of the ones made to the new creatives endpoint.

Example request:
{
uri: 'https://api.linkedin.com/rest/creatives',
method: 'POST',
headers: {
Authorization: 'Bearer {{access_token}}',
Host: 'api.linkedin.com',
'X-HTTP-Method-Override': 'GET',
'Content-Type': 'application/x-www-form-urlencoded',
'LinkedIn-Version': '202207'
},
body: 'q=search&search.reference.value=urn%3Ali%3Aorganization%{{organisation id}}&search.id.values%5B0%5D={{id}}&search.id.values%5B1%5D={{id}}&count=100',
}

Is there a known issue with the new creatives API, or is there something that we need to pay special attention to ?

I got an answer from LinkedIn support, and they pointed me to this documentation: https://learn.microsoft.com/en-us/linkedin/marketing/integrations/ads/account-structure/create-and-manage-creatives-new?view=li-lms-2022-08&tabs=curl#search-for-creatives
