I’m working with a script in Adobe Illustrator to import CSV files and assign their values to variables in a document. The script loads the CSV files correctly, but when I try to apply the variables to an Illustrator document, I receive an error saying “Error: No document found” or “Error: The dataset file is invalid.”
I’ve verified that I always have a document open in Illustrator before attempting to apply the variables, but it seems like the script isn't recognizing the document properly.
Details:
The script loads the CSV files and shows the variables in the list.
The Illustrator document is always open.
The code uses the doc.importVariables() function to apply the variables to the document.
The specific error occurs when trying to apply the CSV data to the document, even though the CSV file loads correctly.
I’ve tried the following methods:
Restarting Illustrator.
Opening different Illustrator documents.
Checking that the variables are correctly assigned and there are no issues with the CSV file or data format.
What could be causing Illustrator to not recognize the document when trying to apply variables from a CSV file? How can I fix this issue to ensure the document is properly linked with the variables loaded from the CSV?

if you change the Window type to "dialog" the script works correctly, right?
windows of type Palette are not as straight forward as Dialogs. Palettes don't have access to Illustrator documents and viceversa. To make the Palette and Illustrator see each other you must send messages via BridgeTalk.
here's one sample of how the system works, let me know if you can apply the same concept to your script and post back if you have questions
