我希望完全省略我不使用的变量以避免错误，例如"Variable "$eventId" got invalid value ""; Int cannot represent non-integer value: "

以这个查询为例：

//gql``
query($orderBy: [AwardsOrderBy!], $limit: Int!, $eventId: Int) {
   allAwards(first: $limit, orderBy: $orderBy, filter: { eventId: { equalTo: $eventId } }) {

//query variables and query
limit = 40
orderBy = "DATE_DESC"
eventId = falsey
useQuery(AWARDS, { variables: { limit, orderBy, eventId } })

现在我假设这个查询可以正常工作，但过滤的 eventId 部分将被完全忽略。

有没有办法用graphQL和postgraphile解决这个问题

这是我当前的解决方案，无需考虑，我只需要它现在就可以工作：

  const queryVariables = [
    ...(eventId ? [`eventId: { equalTo: $eventId}`] : []),
    ...(awardTypeId ? [`awardTypeId: { equalTo: $awardTypeId}`] : []),
  ]
  const filterVariables = [...(eventId ? [`$eventId: Int`] : []), ...(awardTypeId ? [`$awardTypeId: Int`] : [])]

  const filter = queryVariables.length
    ? `, filter: { ${queryVariables.map((a, index) => {
        return `${a}${queryVariables.length !== index + 1 ? ', ' : ''}`
      })} }`
    : ''

  const query = `
    query($orderBy: [AwardsOrderBy!], $limit: Int!${queryVariables.length ? `, ${filterVariables}` : ''}) {
      allAwards(first: $limit, orderBy: $orderBy${filter}) {
        edges {

///example output:
query($orderBy: [AwardsOrderBy!], $limit: Int!, $awardTypeId: Int) {
  allAwards(first: $limit, orderBy: $orderBy, filter: { awardTypeId: { equalTo: $awardTypeId} }) {
