JSON Parse error in bookkeeping query

[simonerom]

Querying bookkeeping data at https://analytics.iotexscan.io stopped working:

{ 
  delegate(startEpoch:13512, epochCount:528, delegateName:"iotexlab") {   
    bookkeeping(percentage:90,includeFoundationBonus:false) { 
      rewardDistribution { 
        voterEthAddress,amount 
      } 
    } 
  } 
}

gives the following error, regardless of the epoch count:

{
  "error": "JSON Parse error: Unrecognized token '<'"
}

Synced offline, problem resolved. There are two issues in this query:

1. rewardDistribution needs an explicit parameter "pagination"
2. "voterEthAddress,amount" should be in two lines without comma

Reopening this issue again as it seems it's not working again even with "syntax-fixed" code:

query 
{ 
  delegate(startEpoch:13512, epochCount:528, delegateName:"iotexlab") {   
    bookkeeping(percentage:90,includeFoundationBonus:false) {
      exist
      rewardDistribution(pagination: {first: 250, skip: 0}) { 
        voterEthAddress
        amount 
      } 
    } 
  } 
}

while it worked yesterday, it's giving the JSON Parse error again now
