We are calling Companies House API’s which was working fine for few days. But from 12/09/2025 it started giving us the error “exception Cannot invoke “uk.gov.companieshouse.authentication.models.Oauth2AuthorisationsDao.getRefreshTokenPassword()” because “oad” is null”.
Url we are trying to call : /oauth2/token
