How to access filename or Key from File Resource input without creating metadata?

Hi Xano Community,

I'm working on uploading files directly to S3 and need to access the filename from a File Resource input to format my S3 file key.

I want to avoid storing the file in Xano's storage first - I just need to read the filename or other properties from the file resource input to construct my S3 path.

When I debug, I can see the file resource is a base64 encoded string, but I'm not sure how to extract the original filename without using Create Attachment Metadata (which stores the file in Xano).

Is there a way to access the filename property directly from a File Resource input before creating metadata?

Any help would be appreciated!

Thanks
