Warning: Internal error, please report: Dereferencing a non-pointer - I would upload the files but I’m a new user so it won’t let me.

Does anyone know how I can fix this??

check your element input list, make sure there is no null

@daninet thanks for commenting. I have included links to the files. I’m relatively new to Dynamo, so if you could check it, that would be brilliant.

@daninet this is the door I’m using


#5

The input element was disconnected from the next node. There was null input, that’s why you got the error.

After this it run without problem.

@daninet It ran once I reconnected them, but now it has created all my new doors, but they are all the size of the last door in the excel file. Any idea why? Or how to fix it?

Post a camera export of your graph please.

I’m a new user, so it doesn’t let me post pictures or attachments. I did solve the problem though. I didn’t know that I had to set the level correctly to get the input values from excel. Thanks for your help.

Check how list levels are working.
