Rename grid object

Im trying to rename a grid object with the command SetParameterByName. When I create a grid object as an output from a python script and use this as an input to a second python script it works. But when I use the same code in the first Python script it gives an error that a grid object doesnt have the SetParameterByName method. Does anyone have an idea why this is happening/ how it can be solved in one python code block? underneath the working and failing codes printscreen + copied code.

#Assign your output to the OUT variable.

Hi @wouter.hilhorst

Try the below code in your last line. See if that helps.

OUT=[ele.LookupParameter("Name").Set("Test") for ele in Lijst3]

Thanks! I was just watching a YouTube video about this. It works better when it directly communicates with the API.
