Struggling encoding params

[kylelangham]

Hello, I'm struggling to understand how to encode the params correctly for a types record. I'm trying to query the list_neurons method of 'rrkah-fqaaa-aaaaa-aaaaq-cai' (canlista). I've tried multiple combinations for the encoding, but receive errors similar to below.

`from ic.client import Client from ic.identity import Identity from ic.agent import Agent from ic.candid import encode, decode, Types

iden = Identity() client = Client(url = "https://ic0.app") agent = Agent(iden, client) params = [{'type': Types.Record({'name':Types.Text, 'assets': Types.Nat}), 'value': {'name': 'neuron_ids','assets': 4009}},{'type': Types.Bool, 'value': True}] params = encode(params) can_id = 'rrkah-fqaaa-aaaaa-aaaaq-cai' function = 'list_neurons' response = agent.query_raw(can_id, function, params) print(response) `

Error: IC0503: Canister rrkah-fqaaa-aaaaa-aaaaq-cai trapped explicitly: Panicked at 'Deserialization Failed: "Fail to decode argument 0 from table0 to record { neuron_ids : vec nat64; include_neurons_readable_by_caller : bool }"', /ic/rs/rust_canisters/dfn_core/src/endpoint.rs:34:41

You probably want something like this. This works for me.

from ic.client import Client
from ic.identity import Identity
from ic.agent import Agent
from ic.candid import encode, decode, Types

iden = Identity()
client = Client(url = "https://ic0.app")
agent = Agent(iden, client)

types = Types.Record({
        'neuron_ids':Types.Vec(Types.Nat64),
        'include_neurons_readable_by_caller': Types.Bool,
})

values = {
        'neuron_ids':[4008],
        'include_neurons_readable_by_caller': False,
}

params = [{'type': types, 'value': values}]
params = encode(params)
can_id = 'rrkah-fqaaa-aaaaa-aaaaq-cai'
function = 'list_neurons'
response = agent.query_raw(can_id, function, params)

That did the trick! Thanks!
