Hello, I am trying to add a SAML Inline Hook. I have a SAML Application configured, and a user assigned to this application. I create a hook pointing a node express app, responding a very simple ‘add’ command, just to test. I use the “Preview” tab of the SAML Inline Hook. It generates the request for the user and a the SAML application I provisioned. When I click on the “Preview Response” button, I simply get a “Bad Request” error. When I go into the System Logs, I see there is an error, with no further details. When I copy the generated request from the Preview section into Postman, and I use the URL I configured in the inline hook, I get my json payload. My question is: how can I troubleshoot this? Thanks! ---

If either of you have a support entitlement (paid account required), I would recommend [opening a support case](https://support.okta.com/help/s/article/How-to-Create-a-Support-Case?language=en_US) so someone can review the logs for your org and provide guidance ---
