Value cannot be null. Parameter name: Input [_model] is an invalid value null error

@mostapha, I’m trying to use the PO Model component to bring in my model built in the Rhino plugin. I’m getting the error “1. Value cannot be null. Parameter name: Input [_model] is an invalid value null”.

Does this error mean that there is something wrong with the model?

Hi @chriss, this was a bug that @mingbo fixed recently. Installing the latest version should resolve the issue.

I’ve just updated Ladybug tools, and reinserted the Pollination component again (but still says version 0.8.2 of the recipe). Still getting the error. Which components do I need to update and how do I do this?

Hi @chriss, can you share your model with us privately for testing?

It’s a bug that was fixed in the Rhino plugin. Doesn’t have to do with the recipe. What version of the Rhino plugin do you have? You can use the PO_PluginInfo command to see the installed version.

Solved it! I downloaded the new version of the Rhino plugin and now everything works. Thanks for the help!
