Issue
Some users of the Business Edition set up the SSO integration, and authenticate successfully, but then they try to access their app from their IdP and get the error Invalid request. This article explains why users are experiencing this issue.
For example, a user that is using SAML, tried to click the app from Okta, and received this error.
Resolution
We currently do not support IdP-initiated authentication, but we have this feature request on our roadmap: https://github.com/appsmithorg/appsmith/issues/16339
We encourage our users to upvote the GitHub issue and add a comment with the use case to help us prioritize it.
