[gatsby-plugin-image] layout: FLUID doesn't work

[adiusz]

I copied this query from https://www.gatsbyjs.com/plugins/@gromy/gatsby-plugin-image/#graphql-resolver

coverImage: file(relativePath: { eq: "plant.jpg" }) {
  childImageSharp {
    gatsbyImageData(maxWidth: 720, layout: FLUID, placeholder: TRACED_SVG)
  }
}

and got this error:

Unknown argument "maxWidth" on field "ImageSharp.gatsbyImageData". Did you
mean "width"?  graphql/template-strings

When I replace FLUID with FIXED and maxWidth with width everything works fine, except the image is not displaying properly.

Note: I'm using background image example from here: https://www.gatsbyjs.com/docs/how-to/images-and-media/using-gatsby-plugin-image/#background-images

You're referencing the wrong package (an outdated fork). Here's the correct package and its README: https://www.gatsbyjs.com/plugins/gatsby-plugin-image/

I'm wondering why you don't put some note on that article's top that it's outdated. Would be a huge help.
Anyway thanks for helping

It's nothing we can fix, the npm usee gromy needs to remove their forked published package
