Call to a member function getUID() on null #127

tempuser779 · 2017-10-05T11:09:40Z

Steps to reproduce

took fresh vbox ubuntu server 16.04.3 installation, then nextcloud 12.0.3 from .zip installed as described in admin docs, after that docker with collabora pulled and ran in here. nextcloud is accessible through nginx reverse proxy on another machine, the same is collabora, as we do not have necessary certificates on them - all letsencrypt certs are on nginx proxy. everything works fine through the internet.
we have another similar vbox container with nextcloud 12.0.3 in it. I share a folder from this container to the first container. Get php-notification about a share in the first container, accept it. It's ok, I can see shared folders and files.
Trying to open any local file via collabora in the first container - it works. Trying to open any shared file in the first container via collabora and get "internal server error" and all other stuff.
I spent much time on this already. Seems that I should know php for further digging, as the problem is in generating tokens, but I am not a php-man unfortunately.
used browser - Firefox 55.0.2 (64-bit)
yes, and it might be important that when I reshare that shared folder inside the first container collabora opens it normally
I initially reported this issue in https://github.com/nextcloud/server/issues/. A guy from there told me to tell you the following: You may include the information that

richdocuments/lib/TokenManager.php

Line 69 in aa4df2e

public function getToken($fileId, $shareToken = null) {

is not ready for "guests"

Expected behaviour

A shared file should become editable via collabora

Actual behaviour

Instead this I get these mistakes (some in russian, but probably there s no difference for understanding):

Внутренняя ошибка сервера ## (internal server error contact adminstrator and all other typical)

Same problem here. NC 12.0.5, richdocuments 1.12.40, CODE 3.0.0. Trying to open a file that was shared from a different NC instance throws the mentioned error.

Some thoughts: If I deactivate richdocuments and use the documents app instead, it seems to use me (the logged-in user) for the owner; this feels like a sensible default. Could richdocuments behave the same if it can't determine the real (remote) owner?

    114                         #$owneruid = $file->getOwner()->getUID();
    115                         if ($fgo = $file->getOwner()) {
    116                                 $owneruid = $fgo->getUID();
    117                         } else {
    118                                 $owneruid = $this->userId;
    119                         }

At least for me, this hack worked.

I am also having the same issue. It can also be triggered by a local link share, which is then added by a local user to his personal folder.
