GIF image format fails and displays a fallback 11ty image

[murtuzaalisurti]

11ty: v3.0
11ty-image: v6.0.1

Image definition (in markdown):

![alt](https://res.cloudinary.com/dfue3cfts/image/upload/v1738860609/Syntackle/Posts/Screen_Cast_2025-02-06_at_10.18.49_PM_nrhnla.gif)

Plugin definition:

eleventyConfig.addPlugin(eleventyImageTransformPlugin, {
    formats: ["avif", "gif", "webp", "png", "jpeg"],
    sharpOptions: {
        animated: true,
    }
});

Output (getting a 500):

<picture>
    <source type="image/webp" srcset="/.11ty/image/?src=https%3A%2F%2Fres.cloudinary.com%2Fdfue3cfts%2Fimage%2Fupload%2Fv1738860609%2FSyntackle%2FPosts%2FScreen_Cast_2025-02-06_at_10.18.49_PM_nrhnla.gif&amp;width=680&amp;format=webp&amp;via=transform 680w">

Same for me:

	eleventyConfig.addPlugin(eleventyImageTransformPlugin, {
		// Output formats for each image.
		formats: ["avif", "webp", "gif", "auto"],

		// widths: ["auto"],

		failOnError: false,
		htmlOptions: {
			imgAttributes: {
				// e.g. <img loading decoding> assigned on the HTML tag will override these values.
				loading: "lazy",
				decoding: "async",
			}
		},

		sharpOptions: {
			animated: true,
		},
	});

with

<img src="./svg-favicons.gif" alt="Light and dark mode SVG favicons in Safari, Chrome, and Firefox">

falls back to the 11ty image.

Version: "@11ty/eleventy-img": "^6.0.1"

A +1 to this, also not having (animated) GIFs being transformed when using the HTML Transform feature, using a similar configuration to the comment above.
