Error: simplexml_load_string() + Exception: Call to a member function xpath() on bool #1599

I have updated, after a few months, my server for NextCloud and, with the 4.1.1 version of richdocuments, I get the following errors:

Error: simplexml_load_string(): Entity: line 1: parser error : Start tag expected, '<' not found at /var/www/nextcloud/apps/richdocuments/lib/WOPI/Parser.php#47

Error: simplexml_load_string(): Permissions-Policy: interest-cohort=() at /var/www/nextcloud/apps/richdocuments/lib/WOPI/Parser.php#47

Error: simplexml_load_string(): ^ at /var/www/nextcloud/apps/richdocuments/lib/WOPI/Parser.php#47

for all three the description is as follows:

and then again:

The consequence is that, while everything else works, Collabora Online is no longer reachable.

The link https://my-site/loleaflet/dist/admin/admin.html displays the empty dashboard with the writing: Server has been shut down; please reload the page.

In NextCloud, on the page https://my-site/settings/admin/richdocuments, the message appears: Could not establish connection to the Collabora Online server

The configurations are the same as when the site was working.

Hello i have the same problem in Nextcloud 21.0.4, Collabora working perfectly before i dont know what is the problem. Some can help with this bug please.

juliusknorr commented 3 years ago

Could you chek the output of curl -k localhost:9980/hosting/discovery when executing that on the nextcloud server?

danir-de commented 3 years ago

We're getting a curl: (7) Failed to connect to localhost port 9980: Connection refused. I'm not really sure what to expect, the web server only runs on port 443 and 80.

I have the same issue. Nextcloud 21.0.5, Collabora Online 4.2.3, Collabora Online - Built-in CODE Server 6.4.1303.

When checking settings/admin/richdocuments, it says that it cannot connect to the Collabora server (I'm using CODE), and points me to https://www.collaboraoffice.com/online/connecting-collabora-online-built-in-code-server-with-nginx/. Maybe this is important?

turion commented 3 years ago

Either way, for me this location is set (since I'm using NixOS) as far as I understand, and still it doesn't work. In particular, the relevant line is location ~ ^\/(?:index|remote|public|cron|core\/ajax\/update|status|ocs\/v[12]|updater\/.+|oc[ms]-provider\/.+|.+\/richdocumentscode\/proxy)\.php(?:$|\/) { include /nix/store/syg3lx68fls35wwzqnfg7s8snsl3b4a3-nginx-1.20.1/conf/fastcgi.conf;, containing the string /richdocumentscode\/proxy which I believe is necessary.

juliusknorr commented 3 years ago

CODE and the built-in CODE server are two separate things. CODE in general just specifies that you are using the Collabora Online Development Edition.

You can either run it using a native package that can be installed through your distributions package manager or via Docker. Or you can use the built-in CODE server is a Nextcloud app that proxies the requests to a Collabora process that is started in the background https://github.com/CollaboraOnline/richdocumentscode.

If you are using the built-in code server, please check the output of the following urls:

https://nextcloud.example.com/apps/richdocumentscode/proxy.php?status https://nextcloud.example.com/apps/richdocumentscode/proxy.php?req=/hosting/discovery

Seems I face a related issue (NC 25.0.5.1, standalone CODE 22.05.12.4). simplexml_load_string($discovery) in line 47 of lib/WOPI/Parser.php returns false, obviously because $discovery contains JSON data (returned from the CODE server, so network connection is not an issue), not XML.

daCaPo commented 1 year ago

Well, I found my mistake: There was the path /hosting/capabilities given in the server address field on /settings/admin/richdocuments - copy-paste error, not so obviuos as not visible in the narrow text box - sorry for this false alarm.

The link https://my-site/loleaflet/dist/admin/admin.html displays the empty dashboard with the writing: Server has been shut down; please reload the page.

This suggests something was going on with the CODE server. This app (richdocuments) is just the integration app. You'd have to troubleshoot your CODE server installation: https://sdk.collaboraonline.com/docs/installation/Collabora_Online_Troubleshooting_Guide.html#troubleshooting

In NextCloud, on the page https://my-site/settings/admin/richdocuments, the message appears: Could not establish connection to the Collabora Online server

Which is what I'd expect given the described circumstances.

The errors in the logs are merely symptoms of the above problem.

The logging in this area is a bit better today than it was at the time of your original report, but we're still not going to be able to overcome the CODE server not functioning.
