FYI: Traefik 3.6.4 breaks pigallery2 (and more)

[mrtnbr]

After some annoying troubleshooting, I figured out that an update to Traefik caused pigallery2 to start misbehaving/not loading galleries.

Beware if you use Traefik and pigallery2 :)

Do I read it correctly that it will stay as it is and won't get fixed?

Most likely this causing the problem:

pigallery2/src/frontend/app/ui/gallery/contentLoader.service.ts

Lines 109 to 113 in d5a5e0a

	cw = await this.networkService.getJson<PackedContentWrapperWithError>(
	'/gallery/content/' + encodeURIComponent(directoryName),
	params
	);
	} catch (e) {

It was added in 355df1d for issue: #272

if we set up proper tests that cover the issue in 272 (and anything else that is reasonable), we can try to reverse encode the content for the banned characters

I had to read a lot, but that would be my interpretation of their reaction as well. It would be good to try and fix it in pigallery2, since I suspect this will affect quite a few pigallery2 users once they upgrade Traefik.

I can't help you with the fix I'm afraid, but I would be more than happy to test a fix :)

Thanks a lot for following up to this!

Hey, I just noticed I'm having this problem too! I applied the workaround but I'd like to revert it asap as it's reducing security, is it planned ?

[bpatrik]

Most likely I won't have the bandwidth to fix it in the near future.

What about using encodeURI instead of encodeURIComponent?
