This issue is not happening for all cases and its only occuring in one production case. And also there are no when rules been referenced in dynamic layouts in that harness.

Any idea on how to resolve this issue?

Thanks..

Hello, 

What Platform version is it? So I guess the Obj-Open-By-Handle is working but the review harness failing. Can you share your tracer output. 

Can you check if you have any data differences between working and not working cases.

You would need to check the entire set logs to check if some other error around the same timestamp is triggering this. 

Like Marc said this could also be contributed by some "data" that is particular to the case in which this is observed. Comparing working and non-working could also help.

@MarissaRogers  @MarcLasserre_GCS @Krithiga_GCS 

Yes, I reviewed the log and this only happened one time for particular case and showed case status as "harness fail"

Rest I am able to create/open other cases.

I got this below error from logs but I am not understanding for what reason case got fail.

Section 'PerformPhaseTwo' execution error on page 'pyWorkPage' of class  'XXX-YYY-ZZZ'. : Component stack mismatch  {"NTId":"1619088955703000","NTRef":"97171b9992d332f8bef45d200123cb75_2","pyName":"pxNonTemplate"}!!!!==== {"containerType":"NOHEADER","containerStyle":"","isClientWhen":false,"isVisibilityOption":"", "pyName":"pxHarnessContainer","pyTemplates":[{"pxReferencedId":"acb57f58c875d41ef9fc4f4e5f095799_3", "pyName":"pxSection"}]}

@sadhanag   This might be because of visible when conditions on the layouts, which can be confirmed by tracing and see whether that when rule are you able to run from rule-form by selecting the same page and thread. Probably you need to change label name in the when expression with A, B to regenerate the expression.
