Variable Sharing from R to CSharp

[christiandmiles]

Describe the bug

Using the following dockerfile:

FROM jupyter/datascience-notebook:x86_64-ubuntu-22.04

USER root
ENV GRANT_SUDO=yes
RUN sudo apt-get update && sudo apt-get install -y dotnet-sdk-8.0
USER jovyan
RUN dotnet tool install -g Microsoft.dotnet-interactive && export PATH="$PATH:/home/jovyan/.dotnet/tools" && dotnet interactive jupyter install
ENV PATH="$PATH:/home/jovyan/.dotnet/tools"

In a dotnet notebook, I can use R with #!connect jupyter --kernel-name Rkernel --kernel-spec ir and then !#Rkernel

I can also share variables from c# to R but when I try and share a variable from R to c# I get the error in the screenshot below. This appears to happen with data tables but also if I convert it to json.

Please complete the following:

Which version of .NET Interactive are you using? (In a notebook, run the #!about magic command. ): 1.0.552801+0365de1427f040dd36e5bfcf29320582e83c059e
