Apollo-client (react) - Update on create mutation - "Can't find field Fund({}) on object (ROOT_QUERY)"

Using: "react-apollo": "^1.4.3"

In the parent component I query using GraphQL a parent node 'Fund' with children 'fundQuarterlyMetric'. This returns data in the following format:

{      
  id
  name
  ...
  fundQuarterlyMetrics (orderBy: asAtDate_ASC) {
    id
    year
    quarter
    ...
  }
}

When I try to create a new fundQuarterlyMetrics I have to update the local store on react-apollo using the update feature (Apollo Client docs). It gives me an error:

   Can't find field Fund({}) on object (ROOT_QUERY) {
     "Fund({\"id\":\"cj57hpfips0x7014414u5tk8m\"})": {
     "type": "id",
     "id": "Fund:cj57hpfips0x7014414u5tk8m",
     "generated": false
    }

The thing is, is that when I console.log the proxy, I can see the Fund and it's children under data.... not sure what to do..

UPDATE following comment:

Here is the parent component data request:

export const fundPageQuery = gql`
 query Fund($fundId: ID!) {
Fund(id: $fundId) {
  id
  name
  ....other variables
  fundQuarterlyMetrics (orderBy: asAtDate_ASC) {
    id
    year
    quarter
    ....other variables
  }
}

} `;

Here are the options I used:

var optionsForCreateFundMetric = {
 update: (proxy, {data: {createFundMetrics}}) => {
 try {
  console.log('proxy', proxy);
  const data = proxy.readQuery({query: FundQL.fundPageQuery});
  console.log('data', data);
  data.Fund.fundQuarterlyMetrics.push(createFundMetrics);
  proxy.writeQuery({query: FundQL.fundPageQuery, data})
} catch (e) {
  console.log('error adding to store', e);
}

} };

export default compose(
 graphql(FundQL.createFundMetrics, {name: 'createFundMetrics', options: 
 optionsForCreateFundMetric}),
 graphql(FundQL.updateFundMetrics, {name: 'updateFundMetrics'})
 )(FundMetricsForm);

Here is my create mutation:

export const createFundMetrics = gql`
 mutation createFundQuarterlyMetric(
$fundId: ID
$year: Int!
$quarter: FUND_QUARTERLY_METRIC_QUARTER!
$netIRR: Float!
$tvpi: Float!
$rvpi: Float!
$dpi: Float!
$asAtDate: DateTime
$calledThisQuarter: Float!
$distributedThisQuarter: Float!
$cumulativeCalled: Float!
$cumulativeDistributed: Float!
$limitedPartnersNAV: Float!
$quarterlyValuationChangeLCY: Float
$quarterlyTotalReturn: Float
 ) {
createFundQuarterlyMetric(
  fundId: $fundId
  year: $year
  quarter: $quarter
  netIRR: $netIRR
  tvpi: $tvpi
  rvpi: $rvpi
  dpi: $dpi
  asAtDate: $asAtDate
  calledThisQuarter: $calledThisQuarter
  distributedThisQuarter: $distributedThisQuarter
  cumulativeCalled: $cumulativeCalled
  cumulativeDistributed: $cumulativeDistributed
  limitedPartnersNAV: $limitedPartnersNAV
  quarterlyValuationChangeLCY: $quarterlyValuationChangeLCY
  quarterlyTotalReturn: $quarterlyTotalReturn
) {
  id
  year
  quarter
  netIRR
  tvpi
  rvpi
  dpi
  asAtDate
  calledThisQuarter
  distributedThisQuarter
  cumulativeCalled
  cumulativeDistributed
  limitedPartnersNAV
  quarterlyValuationChangeLCY
  quarterlyTotalReturn
}

} `;

SOLUTION Thanks Daniel - I had to return the fund ID to make it work so thank you!

export default compose(
 graphql(FundQL.createFundMetrics, {name: 'createFundMetrics', options: 
optionsForCreateFundMetric, variables: {fundId: 
createFundQuarterlyMetric.fund.id}}),
 graphql(FundQL.updateFundMetrics, {name: 'updateFundMetrics'})
 )(FundMetricsForm);
