Frida API Monitor API is responding ERROR message for OK response

ENVIRONMENT

OS and Version: Ubuntu 20.04
Python Version: 3.11.9
MobSF Version: v4.0.7

EXPLANATION OF THE ISSUE

I write a method to start Frida Instrumentation

def start_Frida_instrument(host_url, api_key, file_hash, default_hooks='api_monitor,ssl_pinning_bypass,root_bypass,debugger_check_bypass', auxiliary_hooks='', frida_code=''):
    """
    Start Frida to monitor API at runtime.
    @param host_url:
    @param api_key:
    @param file_hash:
    @return:
    """
    print("Starting Frida API instrument...")
    api_url = host_url + "/api/v1/frida/instrument"
    headers = {
        "Authorization": api_key
    }
    data = {
        "hash": file_hash,
        "default_hooks": default_hooks,
        "auxiliary_hooks": auxiliary_hooks,
        "frida_code": frida_code
    }
    try:
        response = requests.post(api_url, headers=headers, data=data)
        if response.status_code == 200:
            return response.json()
        else:
            return {"error": response.json(), "status_code": response.status_code}
    except Exception as e:
        return {"error": str(e)}

However, when I execute this method, the response is {'message': 'Failed to instrument app', 'status': 'ok'}.

Other methods I use are as follows:

def upload_file(host_url, api_key, file_path):
    """
    Upload apk file to the server
    @param host_url: ip:port of the server
    @param api_key: API key of MobSF
    @param file_path: file path of the apk
    @return:
    """
    print("Uploading file")
    multipart_data = MultipartEncoder(fields={'file': (file_path, open(file_path, 'rb'), 'application/octet-stream')})
    headers = {'Content-Type': multipart_data.content_type, 'Authorization': api_key}
    response = requests.post(host_url + '/api/v1/upload', data=multipart_data, headers=headers)
    return response.text

def scan_file(host_url, api_key, file_hash):
    print("Starting static scan...")
    api_url = f"{host_url}/api/v1/scan"

    headers = {
        "Authorization": api_key,
    }

    data = {
        "hash": file_hash,
    }

    try:
        response = requests.post(api_url, headers=headers, data=data)
        if response.status_code == 200:
            return response.json() 
        else:
            return {"error": response.text, "status_code": response.status_code}  
    except Exception as e:
        return {"error": str(e)}  

def start_dynamic_analysis(host_url, api_key, file_hash, re_install=1, install=1):
    """
    Start dynamic analysis.
    @param host_url:
    @param api_key:
    @param file_hash:
    @param re_install:
    @param install:
    @return:
    """
    print("Starting dynamic analysis. Probably several minutes...")
    api_url = host_url + "/api/v1/dynamic/start_analysis"
    headers = {
        "Authorization": api_key
    }

    data = {
        "hash": file_hash,
        "re_install": re_install,
        "install": install
    }

    try:
        response = requests.post(api_url, headers=headers, data=data)
        if response.status_code == 200:
            return response.json()
        else:
            print({"error": response.json(), "status_code": response.status_code})
            return None
    except Exception as e:
        return None

STEPS TO REPRODUCE THE ISSUE

1. Upload an APK file via api.
2. Scan the APK and get the hash.
3. Start dynamic analysis via api.
4. Run the start_Frida_instrument method.
