Hello ,I tried the same with both pykx 2.2.0 /2.3.0 , python 3.10.9 , Flask 3.0.2, I can’t able to connect with port 5000.
```
from flask import Flask 
import pykx as kx 
import json as j 
app = Flask(__name__) 

@app.route("/") 
def hello_kx(): 
     import pykx as kx 
     qcon=kx.QConnection(host='localhost', port=5000) 
     tables=qcon("tables[]").py() 
     import json as j 
     print(j.dumps(ports)) 
     return tables 

if __name__ == '__main__': 
     app.run(host='127.0.0.1', debug=True, port=8100)
```
I got this error:

if q(‘{.pykx.util.isw x}’, self).py():

File “/rxds/rxds_offerings/datagen/env/lib/python3.10/site-packages/pykx/embedded_q.py”, line 226, in __call__return factory(result, False)

File “pykx/_wrappers.pyx”, line 507, in pykx._wrappers._factory

File “pykx/_wrappers.pyx”, line 500, in pykx._wrappers.factory

pykx.exceptions.QError: .pykx.util.isw

the same code I just run python without flask it return values.
```
import pykx as kx 
import json 

def hello_kx(): 
     qcon=kx.QConnection(host='localhost', port=5000) 
     tables=qcon("tables[]").py() 
     import json 
     return json.dumps(tables)

a=hello_kx() 
print(a)
```
