Hi, Im facing this issue when i'm retrieving a list of data from an integration and casting it to a data subset when i try to acces a especific id in a expression rule everything works perfectly
and it returns an id but when i do the same thing on a process model it throws me this error that you see i tried many ways of getting this to work and nothing. what could it be the problem that i'm facing ?
below how looks like the expression rule when i use the process model to get the values
this doesn't work either

Hi, I would suggest you check your data from integration. I can see your rule is not able to index "data", So try to check on that .
This is a lot of information to try to piece together... but the one thing I notice in your error message is you're trying to call pv!invoicesList.data[1] - which of course will fail if pv!invoicesList is blank OR if the .data property is empty. Can you confirm whether this PV actually has a value in your process instance? You didn't show any confirmation of this either way.
off course it has data this is the data it has. I know it is too much information but i wanted to be as clear as posible
It looks like ,you have nested dictionaries. I think you need to deal with your data in a right manner so that indexing can be easy.
Yes, in this case I'd strongly suggest doing some further digesting of the data within the Expression Rule and direct the output into a PV which is an array of a specific CDT, rather than the DataSubset type.
thanks You all Gopalk and Mike Schmitt i did tried wih a CDT and now is working perfectly!
