[Smush Pro] "File Path is empty" issue

When i go for individual smush image – it gives me – "File Path is empty" issue. If i go for bulk smush it gives me list of images with its server path – /var/ww/html/ … and message "Could not find " – whereas my images are on s3 bucket. I have enabled required settings from the plugin and also have aws offload plugin activated in website.

Can you please look into it and let me know what is exact issue.

Thanks in advance.
