docs: stringify bigint for typed variables

Hi guys,

I am using typed variables in my GraphQL statement to insert into a table with a BigInt column. The docs say use ‘String’, but with string I get {"errors": [{"extensions": {"path": "$.variableValues.var_contract_id", "code": "parse-failed"}, "message": "expected Text, encountered Number"}]}.

My code is:

    query = """ mutation insert_tbl_rslt_option_price_hist (
    $var_contract_id: bigint!, $var_bid: String!, $var_ask: numeric!, $var_tick_ts: timestamptz!) 
    { insert_tbl_rslt_option_price_hist(objects: {
    contract_id: $var_contract_id, bid: $var_bid, ask: $var_ask, tick_ts: $var_tick_ts
    }) { returning { landed_ts } } } """
    variables = {
        "var_contract_id": conid,
        "var_bid": bid,
        "var_ask": ask,
        "var_tick_ts": tick_ts
    }
    url = 'http://' + os.getenv('HASURA_IP') + ':' + os.getenv('HASURA_INTERNAL_PORT') + '/v1/graphql'
    headers = {
        "content-type": "application/json",
        "x-hasura-admin-secret": os.getenv('HASURA_ADMIN_SECRET')
    }
    request = requests.post(url=url, json={'query': query, 'variables': variables}, headers=headers, timeout=1)

The query works when I use bigint! instead of string (as I would expect 😃 )

Wanted to add that the docs currently are a little confusing. The Hasura Type mentioned is more like the format it expect the variable in and not the GraphQL type to be used. We’ll update the docs to make this more clear

@dvasdekis Take a look at #1504 & #1523 for context. Your value will be saved as bigint in postgres eventually. Its a just a json limitation for which bigints need to be stringified
