Error when adding new field in profile creation by API

Hello everyone,

In the "Profile" resource we have created the extended resource and created new fields. We are also creating profiles through API calling this endpoint https://mc.adobe.io/company/campaign/profileAndServicesExt/profile/.

This is working correctly but we have added a new field to the profile extended resource and we have added the same field to the API and we are getting the following error 'NewField' property is not valid for the 'profile' resource.

It looks like it is not identifying the new field in the API schema? Does anything else have to be done apart from creating it in the resource?

Thanks
