It’s not a big issue, however it should be fixed or noted in the documentation.
If you in your sitemap by accident put a label space = … sitemap will not load,
It should be label= " … So after = you can have as many spaces as you want, but NOT before…
Maybe cross reference it? To also mentioned it in items,sitemap files as well?
it is not explitily written label =“jgskjgks” does not work
because label= "sjdkgsldgjl … does work…
And it is kinda strange that white-spaces are not allowed like in most other languages… so its easy for beginners and even me after not doing OH for a year when coming back to OH I automatically typed label = "foo because that’s how its common in other languages… I do not know hard it is to fix this in the next release of OH.
