This article addresses the intent to restore visibility of Salesforce OmniStudio FlexCards and OmniScript-based Lightning components for multiple end users who share a profile or permission set. Affected users see the component area blank or non-functional with no visible error, while a System Administrator sees the component correctly.
Some users also encounter "ApiQueryException" referencing "OmniInteractionAccessConfig.DeveloperName" in the browser JavaScript console. Trigger conditions include: enabling OmniStudio Metadata (Managed Package vs. Standard Runtime), enabling Enhanced Runtime Performance, deploying new component versions, or going live in a production org where sandbox permission sets were not migrated.
Affects non-administrator profiles and users assigned custom permission sets that lack OmniStudio object access; System Administrators are typically unaffected because their profile grants access to all OmniStudio objects.
Work through the causes in order. Both causes commonly co-occur when new component versions are deployed or you go live.
Cause 1: Affected users are missing OmniStudio object permissions.
Cause 2: Enhanced Runtime Performance is enabled and enforces in-platform access checks that unentitled users fail.
Cause 3: A newly activated component version is not the version users are entitled to see.
Confirm the issue is resolved by logging in as (or having) an affected non-admin user open the Lightning record page (for example the Person Account or patient record) and verifying the Patient Card FlexCard and Assessment component render and function, with no blank area and no "ApiQueryException" in the browser JavaScript console.
