I found two similar discussions that might be related to the issue you're experiencing:

1. Unable to open image: /files/tools - This discussion is still open and was last updated on November 5, 2024.
2. Generate image error - This discussion is also open and was last updated on September 13, 2024.

Regarding your issue with the iteration node not correctly returning the file type, it's important to ensure that the input variable for the iteration node is formatted as a list object. The iteration node processes each element in the input array sequentially, and the input must be an array variable ^[1]. If the file type is not being returned correctly, it might be due to the input not being properly formatted as an array or list.

Additionally, common causes of file type handling errors in the iteration node include issues like the iterator variable not being found or the iterator value not being a list ^[2]. You might want to check these aspects in your setup.
