Hi All,

I am getting this exception when running application through the scripts only on Pega Platform 8.3.1 version with jdk1.8.0_231. Getting this exception not too often but getting this rarely (Ex: 1 out of 400).

Below is the few important lines from log file:

java.lang.RuntimeException: Scalar query .pxFlow().pyFlowParameters.HarnessType on page 'pyWorkPage' of type '###-###-#####' using 1 parameter(s) ([]).

Below screenshot shows 19th step of FinishAssignment activity.

Is anyone know which could be the reason for this exception, please share with me.

Thanks,
