`No value provided for required argument: id` error in graph ql database

Question

Question

• I am tryting to download data from a cryptocurrency exchange "perpetual protocol"
• The API document page is here, which lets you see how the API works.
• Since my main programming language is Python, I am using it to download data but I got the following error message. {'errors': [{'locations': [{'line': 0, 'column': 0}], 'message': 'No value provided for required argument: id'}]}.
• Can anyone tell me how to fix this error to download data, please?

import request

timestamp = 1607904000

graphql_endpoint = 'https://api.thegraph.com/subgraphs/name/perpetual-protocol/perp-position-subgraph'
headers = {"Content-Type": "application/json"}

fundingRateUpdatedEvent_query = """query {
                            fundingRateUpdatedEvent(first: 1000, orderBy:timestamp,orderDirection:asc, where:{timestamp_gt: %i}) {
                                    id
                                    amm

                        }}""" % (timestamp)

request_result = requests.post(graphql_endpoint, json={'query': fundingRateUpdatedEvent_query}, headers=headers)
if request_result.status_code == 200:
    request_result.json()['data']['fundingRateUpdatedEvents']
else:
    raise Exception(f"GraphQL query failed to run by returning code of {request.status_code}.")

• It is weird to me because the following codes below has no problem working. The only difference is the contents in query statement.

Answer 1

You need to pluralize the entity you are querying:

fundingRateUpdatedEvents

I believe we encountered the same issue using the graph!
