- were there any backup db manipulations done on this environment?
- can you check the 'when' rule referenced in your logs?
- is this a newly created rule?
- If you haven't tried yet, can you please do a 'Revalidate And Save' on the Section and when rules to see if that helps.
- Also, please verify and confirm, if you are seeing Nul in the ' o2|| wxpxIsCircumstance wxpxHasQualifiers' rule.
- Can you please run tracer, reproduce the issue and log a support ticket if you require further help.

The root exception indicates that there is an error evaluating the visible when condition for a UI component. It seems like the issue is related to a visible when condition that contains the expression 'o2|| wxpxIsCircumstance wxpxHasQualifiers'. The error message suggests that this expression might be causing an issue with the Auto Stream feature in Pega.
To resolve this issue, you can try the following steps:
- Disable the Auto Stream feature for the problematic UI component.
- Modify the visible when condition by removing the problematic expression.
- Check if any new Pega hotfixes or updates are available that might address this issue.
To disable Auto Stream for a UI component, you can follow these steps:
- Open the relevant section or harness rule.
- Click on the 'Properties' tab.
- Scroll down to the 'Advanced Presentation' section.
- Deselect the 'Auto Stream' option.
After disabling Auto Stream, the UI component should render correctly, even if the visible when condition is incorrect. If you want to modify the visible when condition, you can do so by editing the relevant section or harness rule in the Pega Designer Studio.
