Lineplot's geometric mean throwing 500s with y-axis date vars

Start by reproducing the lineplot geometric mean request with a Date-valued y-axis using the Amazonia ICEMR Brazil Cohort, then follow the Rserve error where Math.Date receives a Date object. Compare it with the successful geometric mean response; done means the Date-axis request no longer returns a 500.

In implementing the new lineplot UI to include Geometric Mean, I encounter a 500 error when the y-axis variable is a Date object. I've included a screenshot showing the request and lineplot config using Amazonia ICEMR Brazil Cohort and the subsequent error log. At the end, I've included a successful response for a lineplot geometric mean request.
