  "did_error": false,

package main

import (
  "context"
  "log"

  "failior/backend/sdk/failiorsdk"
)

func main() {
  tracker := failiorsdk.Track(context.Background(), "graph-123")
  tracker.Node("api")
  tracker.Node("db")
  tracker.End(nil)
  if err := tracker.Err(); err != nil {
    log.Fatal(err)
  }
}
