Runnning NetLogo Mode from Python Throws RuntimeException

Question

I am trying to connect NetLogo from Python. I am following the official pyNetLogo documentation. Here is my code.

import pynetlogo

netlogo = pynetlogo.NetLogoLink(
    gui=True,
    netlogo_home="/home/protik/NetLogo/"
)

netlogo.load_model("../Netlogo-model/ICS1023.nlogo")
netlogo.command("setup")

It starts the NetLogo interface but fails to run the NetLogo model. It throws this following error.

Exception                                 
Traceback (most recent call last)
 File NetLogoLink.java:121, in netLogoLink.NetLogoLink.loadModel()
 
Exception: Java Exception
 
 The above exception was the direct cause of the following exception:
 
 java.lang.RuntimeException
Traceback (most recent call last)
 File ~/anaconda3/envs/netlogo-env/lib/python3.8/site-packages/pynetlogo/core.py:246,
   in NetLogoLink.load_model(self, path)
      245 try:
  --> 246     self.link.loadModel(path)
      247 except jpype.JException as ex:
 
 java.lang.RuntimeException: java.lang.RuntimeException
 
 During handling of the above exception, another exception occurred:
 
NetLogoException                          
  Traceback (most recent call last) Cell In[1], line 8
       1 import pynetlogo
       3 netlogo = pynetlogo.NetLogoLink(
       4     gui=True,
       5     netlogo_home="/home/protik/NetLogo/"
       6 )
 ----> 8 netlogo.load_model("../Netlogo-model/ICS1023.nlogo")
       9 netlogo.command("setup")
 
 File ~/anaconda3/envs/netlogo-env/lib/python3.8/site-packages/pynetlogo/core.py:249,
 in NetLogoLink.load_model(self, path)
     247 except jpype.JException as ex:
     248     print(ex.stacktrace())
 --> 249     raise NetLogoException(str(ex))
 
 NetLogoException: java.lang.RuntimeException

On the NetLogo interface a dialogue box pops up and shows the following line.

error in loading model java.lang.reflect.invocationtargetexception

By the way, the netlogo model itself runs fine. It only creates error while running from Python. I have checked jvm_path which seems to be correct.

/usr/lib/jvm/java-11-openjdk-amd64/lib/server/libjvm.so

What could be the solution?
