[API V2]What is mapping relation between character and event sourceID
I used below graphql query to parse my raid performance. e.g.
query{
reportData{
report(code:"rwG81bzxZvg3mDN9"){
rankings
events(startTime:14089632,endTime:14920070,fightIDs:[84],dataType:Casts,limit:10000,abilityID:28499){
nextPageTimestamp
data
}
}
}
}
There are sourceID from events but it is obviously not mapping to rankings character id.
So how could I find which character cast something according to event sourceId?
How is the event source ID created?
Thanks
