科目的分类账如果您不清楚，请询问我。您正在useQuery中使用变量，这就是为什么会出现错误。参见appolo中的示例。您需要从
useQuery const GET_USERS = gql`query ledger_query($limit: Int!, $offset:Int!) {
account_ledger(limit: $limit, offset: $offset) {
transaction_id
transaction_amount
}
}`;
const { loading, error, data } = useQuery(GET_USERS, {
variables: { limit: 10, offset: 0 },
});
