why i recieved 500 error??????

[NSH531]

code:

@app.route("/hosts/last_seen/<myid>")
def hst(myid):
    F1=falconpy
    F= falconpy.APIHarness(client_id=client_id,client_secret=secret)
    id_list = 'ID1,ID2,ID3'  # Can also pass a list here: ['ID1', 'ID2', 'ID3']
    response = F1.Hosts(client_id=client_id,client_secret=secret)
    d=(datetime.datetime.now().utcnow()).isoformat()

    j=json2html.Json2Html

    last_seen_result = F1.hosts.Hosts.query_devices_by_filter(filter=f"last_seen:<='{d}'+hostname:*'*{myid}*'",sort='hostname.asc')

    return last_seen_result

output- json:

{"body":{"errors":[{"message":"Keyword arguments must be used for this method."}],"resources":[]},"headers":{},"status_code":500}

what's can I to do???

Hi @NSH531 -

response is defined as an instance of the Hosts Service Class. It is properly created (assuming client_id and secret are valid and falconpy is imported outside of this method), but then it goes unused. The call to set last_seen_result is malformed by calling the module, then the class, then the method directly. (The way it is written, it is making a call to an uninstantiated object and does not reference the constructor.)

If you want the call all on one line, it would need to look something like:

last_seen_result = F1.hosts.Hosts(client_id=client_id, client_secret=secret).query_devices_by_filter(filter=f"hostname:*'*{myid}*'",sort='hostname.asc')

I don't recommend that pattern, as it is difficult to read. If I were to refactor the method above, it would look something like this:

# Import the Service Class at the top of the file
from falconpy import Hosts

# Other code happens here, including the retrieval of our client_id and secret.
hosts_sdk = Hosts(client_id=client_id, client_secret=secret)
# This object is then available to our method when it is called.
# ... other code and methods

# Note: You don't need to filter for last_seen before "now". That is the same as the default.
@app.route("/hosts/last_seen/<myid>")
def hst(myid: str) -> dict:
    return hosts_sdk.query_devices_by_filter(filter=f"hostname:*'*{myid}*'", sort='hostname.asc')

Thank you for the question!
