I am doing operations on azure DPS via REST apis. I am able to post a new provision successfully in "Create new individual enrollment", via REST API.The Url is used is, "https://name.azure-devices-provisioning.net/enrollments/registrationId?api-version=2019-03-31";. My current task is to update the certificate for an individual enrollment in DPS. I am extracting the body of the certificate and attaching it to the request body and doing the PUT operation. But I am getting an error saying "Enrollment already exists with different cert info". I am providing the content-type and authorization sas token as headers. And in request body, I am passing the eTag along. I guess I have cleared all the pre-requisites for an update operation. Please help me to understand if I am doing something wrong here. Thanks in advance!
