Login failure in the Identity Platform (IDP) registration journey

Hey team,

We are currently setting up a registration journey for end-users in our ForgeRock Identity Platform tenant. We are using the journey outlined below and have attached the respective node configurations.

However, during testing, we consistently encounter a prompt for login failure. In the AM debug logs, we’re seeing an error message stating ‘HTTP post may not be null.’ I’ve attached a screenshot of the debug log for reference.

Any assistance with this issue would be greatly appreciated.

Thank you.
