Error reference not set to an instance of an object

Hi Everyone!
I have a problem with dynamo, when i debug me package it show error in my screen dynamo. I’m still using normal dynamo if I don’t debug my code. Has anyone got this error yet, please help me, thanks a lot!


Search the forum for the HelixToolKit error message, it seems to be a dependency on an older DirectX driver.

Thank you. Answers are appreciated!

hmm, this only happens when you are debugging your own package?

What dependencies does your package have? Are you referencing some of Dynamo’s core binaries and leaving copy local set to true in your reference properties?

Maybe an image of you package’s bin folder will help, or a simple GitHub repo that reproduces the issue.

I tried removing all other developers’ packages and it worked fine for me. Thank you very much.
