Invalid plugin options for "gatsby-plugin-manifest": - "value" must contain at least one of [icon, icons]

In your options for the gatsby-plugin-manifest, point to the directory of your logo    

      resolve: `gatsby-plugin-manifest`,
      options: {
        icon: `src/assets/images/logo.png`, // This path is relative to the root of the site.
            },
