pendingIntent or createCredentialResponse must be specified.

Error message

pendingIntent or createCredentialResponse must be specified.

What it means

Constructor validation in CreateCredentialHandle: both optional fields are unset — no pendingIntent and no createCredentialResponse — while at least one is required for the credential-selector flow to act on the handle.

Solutions

1. Provide a non-null PendingIntent or CreateCredentialResponse when constructing the handle
2. Treat a null-both record as invalid and re-request the credential
