Terminate SoundFlow after executing python script

Hi, I'm using the following script to execute a Python script. The problem is that SoundFlow is not terminating, and the icon remains blue.

function runPythonScript({ scriptPath, option1, option2, inputPath, outputPath }) {
    const result = sf.system.exec({ commandLine: `python3 "${scriptPath}" -option_1 ${option1} -option_2 ${option2} '${inputPath}' '${outputPath}'` });
    while (!result) sf.wait({ intervalMs: 50 });
    if (result.exitCode > 0) throw `Error Processing Python Script\nExit Code: ${result.exitCode}\nStandardError:\n${result.standardError}`;
}

const myPythonScript = "/Volumes/Artlist Audio All/Artlist NAS 23/POST MASTERING STEMS/SCRIPTS/__PANELS__/NAS Basic Compact.py";
const speed = 2.5;
const pitch = 1.1;
const fileToProcess = "~/Desktop/someWaveFile.wav";
const processedFile = "~/Desktop/someWaveFile_Processed.wav";

runPythonScript({
    scriptPath: myPythonScript,
    option1: speed,
    option2: pitch,
    inputPath: fileToProcess,
    outputPath: processedFile,
});
