I have created a new custom type with an image field. When I try to use certain SVGs in the field I am unable to save the document. I thought this thread may have been related: [How to upload and use SVG?](https://community.prismic.io/t/how-to-upload-and-use-svg/894) But this error is consistent across both Firefox and Chrome. ---

After further investigation, it seems to be linked to whether or not there are explicit `width` and `height` properties on the svg. When missing, the error is triggered. ---

Workaround is to ensure there are explicit `width` _and_ `height` properties on your svg. When either is missing then that dimension is registered as 0px and results in a 400 error when trying to save the document. Would be really helpful if Prismic could add in a more helpful error here, even saying which field was preventing the save would have saved me a lot of time. ---

Hi Joe, Welcome to the Prismic community, Thanks for sharing the workaround but in order to investigate this issue, can you please share with us the name of your repository (in a private message if necessary). As well as the SVG you are trying to upload? It would be also useful if you can add a screenshot of the error you get, and if you are a developer the error you get in your browser console. Looking forward to your reply, Fares ---

Hi @Fares, Thanks for getting back to me. Created a test repository at `svgtest.prismic.io` Two SVGs attached that are identical except one has `width/height` properties and the other doesn't. [Test SVGs.zip](https://community.prismic.io/uploads/short-url/j7EBcWZeqRC3DBgyjhUVWYRBkjc.zip) (919 Bytes) When I save the document with the SVG with no dimensions selected in the image field, all I get is a 400 response in the console. ![Screenshot 2020-11-19 at 14.28.30](https://europe1.discourse-cdn.com/flex013/uploads/prismic/original/2X/2/2c67071e39a707545f4522c45ff7d1f321a5e489.png) When I save the document with the other SVG selected, the document saves. ---

Hi, I've tried to reproduce the issue on my repository and I was able to upload save and publish both SVGs as shown ![Screenshot 2020-11-19 at 16.56.12](https://europe1.discourse-cdn.com/flex013/uploads/prismic/original/2X/f/f1b55a354ecd20ff1c3de87f11b09acb41817b82.png) I will try to clone this test repo you have created to reproduce the issue. ---

That's interesting! When I upload the svg with no dimensions, the preview shows me "0 x 0px" ---

It seems that issue due to a browser issue in Firefox as far as I remember and seem a duplicate of the thread > [@How to upload and use SVG?](https://community.prismic.io/t/how-to-upload-and-use-svg/894/8): > > okay that’s weird! the repo name is truetapegermany thanks! please give me an update once we know what’s going on here. I've tried the repo you have shared and I see the error but when I upload them again using chrome it works. ---

I still get this issue on Chrome in my test repo. ![Screenshot 2020-11-19 at 16.17.04](https://europe1.discourse-cdn.com/flex013/uploads/prismic/original/2X/c/c6a80cb2aa2683d97c11d8a9a827204f5df79491.png) ---

Ah! My bad, that was using the asset uploaded through Firefox. ---

So to summarise: SVGs without width/height properties when uploaded through Firefox cannot be saved in documents (in any browser). So there appears to be an issue with the file upload process. ---

Okay _here_ is the bug in Firefox: > **[700533 - drawImage() fails silently when drawing an SVG image without @width...](https://bugzilla.mozilla.org/show_bug.cgi?id=700533)** > > NEW (nobody) in Core - SVG. Last updated 2020-08-17. ---
