Unable to Link Phr

We had implemented the PHR link process via Aadhar Number using this api endpoint at the last part of the flow in our project

https://healthidsbx.abdm.gov.in/api/v2/account/phr-linked

But couple of days back, it stopped working when registering for new users

now the error we get is:

{
“message”: “PHR-Address is already exist with this document.”,
“code”: “HIS-3007”,
“attribute”: null
}

Request the admins to please identify what the problem is on an urgent basis

Any help is much appreciated
