I tried this method but it didn't work. I am using it in the condition of the statistic collector to only extract the data if token.Pallet.FinalDestination exist. Is it supposed to be objectexists(data.token.labels["Pallet.FinalDestination"])?

When checking for the labels you either do it in two steps: Check if "Pallet" exists, then check if "FinalDestination" exists.

objectexits(data.token.labels["Pallet"]) && objectexits(data.token.Pallet.labels["FinalDestination"])

data.token.Pallet? && data.token.Pallet.FinalDestination?

Or you chain multiple checks together, but this only works with class properties, as described here, so the expression becomes slightly more convoluted.

objectexists(data.token.labels["Pallet"]?.value?.labels["FinalDestination"]?.value)
