I have a customer who is attempting to open my app clip via the default experience web url. Upon tapping the "open" button the user is presented with a "The operation could not be completed. (CPSErrorDomain error 8) I can't find any documentation on the CPSErrorDomain.

My provisioning code works in my main app, but when I try to use it in my app clip it fails with this: The operation couldn’t be completed. (PKPassKitErrorDomain error 2.) I'm having an issue due to how vague this particular error is and how little documentation exists to explain it? I've been looking around the PassKit and Apple Pay documentation for more specific information. But I'm not certain what to do just yet. After provisioning and receiving the digital wallet token, adding the request to the wallet produces the unsupportedVersionError. My initial thought is because the appClip bundle identifier does not match the identifier that the issuer expects, but I'm not entirely sure. I have the entitlement necessary to provision passes on apples end.
