Journeys-Embed FDI report as external URL in a task

Hello,

We're trying to embed an FDI report into a journey using the "External URL" task type. The report is supposed to display information related to the journey's assignee, so the URL is formatted as follows:

https://****/ui/dv/project.jsp?pageid=visualAnalyzer&reportmode=full&reportpath=%2F%40Catalog%2Fshared%2FPersonalizzate%2FProva_Link_Report&p1n=PERSON_ID&p1v={PersonId}

Unfortunately, the report displays all information regardless of the specified person ID.
Do you have any idea how to make it work correctly?

Thanks,

Giada
