Hello,
I have a very strange issue related to Next/image on Netlify. Whenever I use Next/Image on my local machine, there is no issue whatsoever with using Next/image. I have an AWS S3 bucket with my images that I have added as a url in my next.js config. In development mode as well as in an optimized build, these work fine locally. As soon as the _ipx function is in charge on netlify however, no images show up and I get an error that I can’t really debug because it’s seemingly not my code that is the issue.

I use the essential Nextjs plugin (updated yesterday July 27th 2022 to latest version).

Here is the error from the _ipx logs. It repeats for every instance of Next/image whenever an is supposed to load in the browser.

Hi @Emilcrafter

We implemented a fix for this issue today. Do you mind testing this again with the most recent version of our plugin, please?

I am getting this issue on version 4.13.1, which is @latest on npm. Is there another version somewhere?

Hey @Emilcrafter,

Yes, that is the latest version. I tried right now to load your home page with the images but all images seem to load and the function logs seem empty. Do you have a specific image with which this happens?

Hi, I found the error. My next.config.js file had a nullish element in the images.domains array, since I had removed a url and left the comma. This worked using a local next build but did not work with _ipx. Perhaps this is an issue that should be resolved?

I won’t call this an issue per se, but maybe an edge case to support a non-common or a rare use-case. We’ll add this to our discussion with the devs to see if this is something we would be adding support for.
