yet another different behavior compared to CppCode v/s PythonCode

Json File : eqn_with_constants.json
{ "FileType": "HillTau",
"Constants": { "molBase": 100, "KA": 1, "tau": 1.0, "eqBase":0.0002, "eqScale": 2.0},
"Groups": {
"output_g": {
"Species": {"mol": "molBase" },
"Reacs": {
"output": {"subs": ["mol", "input"],

To get equation from json file, we query via e,t = modelpath.eqnInfo.items()

CppCode: returns
name = eq
mol = ['input', 'mol', 'output']
eqnstr = 0.0002 + 2.0 * input + mol + output

In cppCode the constants are replace with values in the 'eqnstr' and consts are not populated

PythonCode: returns
name = eq
mol = ['input', 'mol', 'output']
eqnstr = eqBase + eqScale * input + mol + output
consts = ['eqBase', 'eqScale']
eqnstr = returns exact equation which is written in json file and consts list is populated
