Subject of the issue

When I try to add anything into Organisation I get error "Unexpected token < in JSON at position 0" when I import items they are blank. Normal (personal vault) is working correctly.
I tried removing DB and starting fresh multiple times.

Install method: Docker-Compose
Clients used: Browser
Reverse proxy and version: External Reverse proxy (Apache)

It seems to work for me fine from Firefox, what browser are you using? Do you get any error in the browsers console (F12)?

Any extensions that could be affecting it? I don't see any onloadwff.js file in the web vault.

I think that this one is coming from LastPass...

I tried same process in MS Edge which I do not use at all and it gave me another error

An error has occurred.

I just tried to login into vault with my phone and I can add Item from there If Owner is Organisation. I can also do it from Web assuming that I'm on home screen and I add item from there with different owner. I can also view shared Items. But as soon as I go to Organisation page I cannot add or open anything.

Ok, I'm really sorry, I figured it out. I had RewriteRule for /admin that redirect anyone going through proxy to homepage as security measure. This aperantly affect something on organisation page. I change it to be more specific and not It does work.

Hi @jkalousek, I'm having the same issue right now. But I cant seem to get it working. Could you share your redirect rule?
I have this currently in my Ngninx Proxy conf but it causes the issue above..
location ~ /(admin) {
return 301 https://bitwarden.domain.com/#/;
}
