MediaRequestProtection: An invalid/missing hash value was encountered

[gitnewbie33]

Hi,

I am working on a project with sitecore 9.2 and JSS. I installed Dianoga 4.0.0 for image optimization in development environment.

Some images are getting optimized properly, but for other images I get below error in logs -

ERROR MediaRequestProtection: An invalid/missing hash value was encountered. The expected hash value: 887E26BCD8C75EAB53BDC584A335E9C1. Media URL: /-/jssmedia/projectname/data/media/global/img/site/banners/clip-art/invent-make-change.ashx?h=637&w=1440&hash=F44F69ED2F9DA6026E2C0BE77DA18BD5, Referring URL: http://hostname/en/about

Can you please suggest resolution for this error? Or should I use a different version of Dianoga with Sitecore 9.2 and JSS?

Hi @gitnewbie33 if you have enabled webp, did you override the Sitecore.JavaScriptServices.Media.MediaRequestHandler as mentioned in the readme? Also I've just released 5.0 beta with a lot of bug fixes - would appreciate if you give this a try.

I found an issue that might have been causing this - fixed in 5.0 RC2
