Hi Dipak Waghmare,
Please enable the “Use custom after sign-in logic” option in the Provisioning tab of the SAML configuration.Then, select the SAML.customAfterSignInLogic microflow from the Custom microflow dropdown — instead of calling this microflow manually from another microflow.
Also, ensure the default parameters of this microflow are not deleted or modified, as the SAML module relies on them to function correctly.
This should resolve the issue.
