 ### Fixed
 
 -   An issue where changing the credential metadata URL to an invalid URL, or a URL that does not contain a credential metadata file, would result in an empty screen.
+-   An issue where an invalid Date would result in the epoch timestamp instead of returning an error.
 -   Enabled ID statement checks for Web3 ID proof requests containing account credential statements.
