Copilot ValueError: Schema healthcare1_msft_bronze.substancedefinition is too long to be added in NB

[sharp1FL]

I am trying to use Copilot in a notebook in my HLS public preview workspace.  I get the following error when I execute the Copilot package installation cell.  Any advice on how I can address this?

Thanks.
