I have generated an executable, say,’test(no extension since its Linux) using PyInstaller and stored it in a directory, saydata`.

I have a python program that is as below:

import subprocess
from pathlib import Path
...
def run_exe():
    try:
        # get current directory
        currdir = Path.cwd()
        datadir = currdir / "data"
        #print(currdir)
        #print(datadir)    
        
        process = subprocess.run(["./test"], shell=False, capture_output=True, text=True, cwd=datadir)
        if(process.stderr): 
            print("stderr:", process.stderr)
            return JSONResponse(content={"success": False}, status_code=400)
        if(process.returncode == 0):
            print(process.stdout)
            return JSONResponse(content={"success": True})
    except OSError as e:
        print(e)
    except subprocess.CalledProcessError as e:
        print(e)    
    except Exception as e:
        print(type(e).__name__)  # Prints the name of the exception class
        print(e)  # Prints the exception message

I have tried the following:

1. Putting subprocess.run(["ls"], it shows the correct directory and files including test

2. Putting subprocess.run(["ls", -l"], it shows the execution permission in test

3. I tried moving to the parent directory and running.

4. I tried subprocess.run(["test"] ...) without the ./

With both the ls commands (2 and 3) it prints the output.

Any help will be greatly appreciated. Thanks
