List element of wrong type

[HolQue]

I have an index. I use this index to get a value from a list. This value is an integer. I use this value as index to get a value from a list:

"index"     : 1,
"indexList" : [0,1,2],
"param1"    : ${indexList}[${indexList}[${index}]]

Result:

{'index': 1, 'indexList': [0, 1, 2], 'param1': '1'}

param1 is of data type str. Why this? There is no string conversion involved in the JSON code above.

Expected is integer value 1.

Several combinations of this JSON code can be found in

and

Corresponding lines are commented out. Affected parameters: param03, param11, k20C, k21B
