V13.6.0 UF 13.4.0 I have a two page form which works fine. However if I add the following validation in the Advanced Options, the form can't find the next page when it's requested.

{
  "==": [
    "{password}",
    "{confirmPassword}"
  ]
}

The password and confirmPassword fields are on the second page. The error is "KeyNotFoundException: The given key '90a4c335-34a4-4243-a727-a5b6f1766820' was not present in the dictionary." If I remove the new validation, it's all fine. I've tried regenerating models and rebuilding but to no avail. Anyone else have this issue?
