Genesys Cloud - Main

I start the interaction in an Inbound Message Flow, in a task I add values to a list of participant data, exit the task, and the interaction moves to a Common Flow. When I try to obtain the same participant data using Get Participant Data, no data is returned.
This happens randomly in some interactions.
What could be the problem?
Is there a lack of synchronization?

Good Day Manual

Just to confirm, this does not happen with every single interaction, correct?

I found the following 2 discussions on the community where similar issues where discussed.

Its possible that there is perhaps a delay where the writing data is not yet available when trying to retrieve.  Have you perhaps tried adding a short delay before the "get participant data" in the common flow to see if that helps?
