custom action payload not pulling the timeseries data

We have a journey where we want to include the last transaction date in the payload from timeseries schema that we sent via custom action. We use the following function to pull the last transaction date,

(#{ExperiencePlatform.testFieldGroup.profile.timeSeriesEvents.last().abcCorp.transaction.transactionDate})

But when we see the resulting data it's not pulling the date and always returning nothing. This is happening with all of the fields within timeseries schema.

Is there any other way to get the value from timeseries data within advanced expression while we use custom action?
