Hey @MikeVL!
It looks like there's a problem with your fallback image. Can I take a look at it?
Hey @DarthSim !
I use base64 encoded image in helmchart values

If remove url returns 404, its works well.
Hmm, it seems that everything is ok with it. Which version of imgproxy do you use?
v3.20.0

This is weird as hell. The XML parse error tells about some EXIF stuff, but the fallback image you set to fallbackImage.data is SVG, so it doesn't have EXIF. And if it wasn't SVG, then why would any XML parsing be involved? The saddest part is that I can't reproduce this with your provided data. Do you by any chance use a fork of imgproxy?
I use darthsim/imgproxy:v3.20.0 docker image
Can you try this image sourece?

The same: the fallback image is used without an issue.
Did you try using a fallback image URL instead of base64 data? Maybe it's Helm or K8s messing up with long values, IDK.
I used the URL before, and then changed it to BASE64, and only now I understand that the broken pictures are possibly a cache in CloudFlar, now the pictures are starting to be updated on fallback.
There are errors in the logs, but the fallback picture is displayed normally.
I'll observe some more and write about the results.
