Alteryx server with okta integration saml

I am setting up Alteryx server with Okta auth saml. I am getting blank screen or error 500 when verifying IDP page. one reason i can think of my metadata file is not present in Alteryx server(I am not sure if this is the ONLY reason). I followed the document which is given below. Configuring SAML on Alteryx Server for Okta - Alteryx Community

Can somebody guide me where i need to put my metadata file in Alteryx server. If I enter the metadata url, i am getting 404 error. it should show xml document.

To complete this configuration, you have to follow these steps:

  1. Create the configuration in Platform.
  2. Add the Platform as an app in Okta.
  3. Map attributes in Okta.
  4. Complete the configuration in Platform.
    In Alteryx framework
    Because you have to perform actions in both Platform and in Okta, we recommend that you open them in separate tabs in your browser before you begin the configuration process.
