failed to open database file (Pyscript sqlite3)

I recently started using Py-script for my HTML documents and run into an Error on which , due to the lack of questions on py-script, i couldnt find a solution by researching.

The error message is as following:

JsException(PythonError: Traceback (most recent call last): 
File "/lib/python3.10/site-packages/_pyodide/_base.py", line 429, 
  in eval_code .run(globals, locals) 
File "/lib/python3.10/site-packages/_pyodide/_base.py", line 300, 
  in run coroutine = eval(self.code, globals, locals) 
File "", line 3, 
  in sqlite3.OperationalError: unable to open database file )

I don't know what's the issue , because while running the program normally in python everything works as intended. I tried giving all needed files all permissions(chmod 777), which solved nothing. Thanks for your help in advance.
