Result of uploaded file


the response from function for upload file does not return any value.
How should I know if the file uploaded correctly and the scene loaded successfully?

I am not sure I understand your question. Are you talking about the updateAsync() API function with a parameter of type ‘File’, which allows you to import a file as input of the Grasshopper definition? In that case, the function returns a promise which describes if the update was successful or not, as described in this article, in the section API response after a parameter update.
