@PALLAVIARORA please provide more info than just a log extract. Context will help you get answers from our users .

The error message you’re seeing is typically caused by an attempt to modify a property that is reserved and cannot be changed. This can happen when there is an explicit step that sets the value of the pxObjClass, or when mapping the response to json directly in the Connect REST rule. As a workaround, you can map the response to the clipboard first and then do some post processing to convert the json string to proper property values.

I see that ticket INC-B25043 was created June 19th. On June 27th client confirmed the following:

" the issue seems to be resolved after adding the property in PegaApp-Step-Adjustment. The BIX was ran successfully manually and the file was generated.

Solution type description:

Create a new pagelist property Adjustment mapped with class PegaApp-Step-Adjustment.

Also, in the extract rule, removed the existing property Adjustment and added again so that the new propertyAdjustment mapped with PegaApp-Step-Adjustment is correctly referred.
