When validating my ZIP file (https://h5validator.appspot.com/) I receive following error (the only error) I have.
It seems to be related to the SVGs I use. They are created with Sketch and I do not really see the problem here.
Anyone experienced this and could guide me?
cc:work node is usually reserved for information about the Work (like credit, format etc.). Could it be that sketch is annotating the SVG with
dc:format? Please check your SVG in a text editor. If so… there should be no trouble cleaning out the node and its content
or even the full
<metadata id="license"...> branch
I use this tool for exporting minified / compressed SVGs from Sketch, and I think it removes that cc:work node by default: https://www.sketch.com/extensions/plugins/svgo-compressor/
Thank you @MaxZieb and @Daniel. I checked the SVGs and it seems to come from Inkscape. At least the SVGs who are affected are not the ones exported from Sketch.
Thank you, issue solved.
