Hi,
It will not work without "
Audience (Entity ID)".
You must get this parameter from OKTA.
For more details about how & where to define it in the OKTA, please see:https://help.okta.com/en/prod/Content/Topics/Apps/Apps_App_Integration_Wizard_SAML.htm
"
- Audience URI (SP Entity ID): The intended audience of the SAML assertion. This is usually the Entity ID of your application.
"
Also, pay attention to the "organization-name" that is defined in the OKTA, You must use "
Short Name" and not the "
Company Name"
