Expected or Desired Behavior

I should be able to get a svg preview using getPreview.ashx.

Observed Behavior

In a site collection, I have a svg image in a document library.
I want to be able to see this image when I have a limited access.
I use the /layouts/15/getPreview.ashx handler to do that.

When I get /layouts/15/getPreview.ashx?action=supportedTypes. I see that svg is supported, but when I try to get the svg image via this handler, I have a http 501 response with no body.

Steps to Reproduce

Upload a svg image to a document library (to make things easier, ensure that the site collection url has no weird characters such as spaces or accents).

myImageUrl = Complete image url beginning with https://{tenantName}.sharepoint.com
MYIMAGEURLENCODED = encodeURIComponent(myImageUrl);

GET /layouts/15/getPreview.ashx?path=MYIMAGEURLENCODED

Any help would be appreciated !
Thanks,
Charles

@StfBauer have you tried to get a preview of user uploaded SVG's?

[StfBauer]

getPreview.ashx service is for binary files only.

It won't make sense to use it for Scalable Vector Graphics which is only a text file and rendered by the browsers just like HTML.

The images preview, in the end, would be potentially bigger than the content of the actual SVG file.

I did a short test and when the service is used it only downloads a blank file. I can confirm that this is not supported and doesn't need to support from my point of view.

I haven't tested the action=supportedTypes but it is more a bug that it is listed there as a supported type.
