REST Connector in Qlik Cloud vs GraphQL (XLEDGER)

[johanbystedt]

Hi all, 

I have struck an issue where I sometimes get a parsing error in Qlik Cloud while using the REST API connector (POST)

Background: Qlik Cloud - REST - GraphXL ( the back end system is xLedger)

One of the very simple POST commands to get Customer data is:

{ "query": "{
customers(last: 2) {
edges {
node {
dbId
description
currency {
code
dbId
description
}
email
glObject1 {
code
}
}
}
}
}
"}

It normally works when I create and save the first connection but if I to change anything afterwards ( like number of records to read) it gives me a parsing error.  DCERROR-0071  ( parsing connection string failed: dcaas API call 'POST /v1/data-sources/actions/parse-properties' failed with code: 400

I tried the same qith Qlik Sense Desktop and that seems to work so this indicates a Qlik Cloud error. However it seems to work there also occationally but I have not found any pattern. 

Does anyone have similar experiences?
