cadviewer 9.17.2 doesn't work at nextcloud 24.0.0

[emoxam]

Hello!

i am using nextcloud 24.0.0

I've installed cadviewer 9.17.2 via the apps section.

Uploaded the dwg file but i cannot find how to view it. I can only download it from my nextcloud.

Can you help me ? Thanks

[emoxam]

did a2enmod rewrite it become better - with RewriteCond %{REQUEST_FILENAME} !/apps/cadviewer/converter/php/. RewriteRule . index.php [PT,E=PATH_INFO:$1] i got "The user experience is that the canvas is white and the "loading.." modal will keep appearing on the screen when attempting to load a file." and "details" of dwg and other files shows "Error while loading the file data". No records at logs i found useful. What can i do anymore ? I do all at the https://github.com/CADViewer/NextCloud#4-troubleshooting - it doesn't help.

Hello @emoxam , with the RewriteCond set you should normally see the icons, etc. Have you done the permission setting of the CAD converter ax2023_L64_xx_yy_zz? If a drawing is not being converted this is typically the issue. Try and send the Conversion log, you find from the admin interface Api Conversion Log, or directly in the folder /nextcloud/apps/cadviewer/converter/php/call-Api_conversion_log.txt, the datestamp and content will list if the scripts is executed and the result. Also, if you open the browser developer console, Ctrl+Shift+I and send that trace as .txt, then we can see what the front-end sends to the backend.

Hello @CADViewer Thanks for the answer, i'am out of ideas and almost lost the hope...

1. root@nextcloud:/opt/nextcloud/apps/cadviewer/converter/converters/ax2024/linux# ls -l | grep ax2023_L64_23_12_120 -rwxrwxrwx 1 www-data www-data 95025544 ноя 21 14:52 ax2023_L64_23_12_120

2. Api log is attaching call-Api_Conversion_log.txt

3. F12 - console - save as TXT ? Do I have to do this?

[emoxam]

I take two blocks from /opt/nextcloud/apps/cadviewer/converter/nextcloud_AIO_sample.htaccess

Should I have done it? Or these two should be enough ?

  RewriteCond %{REQUEST_FILENAME} !/apps/cadviewer/converter/php/*\.*
  RewriteRule . index.php [PT,E=PATH_INFO:$1]

[CADViewer]

@emoxam , so the converter is never executed, I noticed something above in RewriteCond settings , are you on ARM architecture? RewriteCond %{REQUEST_FILENAME} !/richdocumentscode(_arm64)?/proxy.php$

Our back-end converter is x86 , so it will not run on an ARM processor. Please let me know.

[emoxam]

@CADViewer No, i'm on x86.

[emoxam]

@CADViewer Did you read my messages ?

[CADViewer]

@emoxam , can you please open the browser developer console, Ctrl+Shift+I, capture the trace where you try to open a drawing, and send that trace as .txt, This will alow to see what the front-end sends to the back-end. You can also send a screenshot of your screen with CADViewer.

[emoxam]

@CADViewer F12 - console - save as TXT ? Do I have to do this?

[CADViewer]

@emoxam , in the console trace, you can see which instructions CADViewer passes on to the server, there will be calls to the php endpoints to do various things, if you isolate those calls, or check the responses, you can see if the rewrite rule is in place, and you can see if there is any server action on the back-end converter, etc. To see the console .txt with traffic will give us some error messages to work with

[emoxam]

nextcloud.integris.ru-1700810751391.log

[CADViewer]

@emoxam , I am not seeing anything in your trace. If you see this image, you will see that there in the console are statements containing CADViewer calls to the server.

[emoxam]

Can you share default .htaccess with me ?

[CADViewer]

On Snap, Ubuntu 22.04 LTS , Nextcloud 7.1.3 , CADViewer v9.19.4

[emoxam]

@CADViewer as a txt file please

[CADViewer]

Snap install .htaccess instance:

[emoxam]

what is it ? After i installing CADViewer via the nextcloud there is a .htaccess on a few pages! Where is can get it without reinstalling CADViewer ? /opt/nextcloud/.htaccess in my case

[CADViewer]

CADViewer does not change your .htaccess file on installation, .htaccess is a control file there is at the top level of a folder, typically it controls settings for an application at that folder, in your case /opt/nextcloud/.htaccess . Check, your rewrite rules in that folder. Basically if there is not a rewrite rule for the location of the CADViewer php scripts, then the front-end CADViewer will not be able to build the menus in cadviewer, nor will it be able to make conversions.

[emoxam]

You are right, don't you have default nextcloud .htaccess ? i deleted mine... Or is it it https://github.com/nextcloud/server/blob/master/.htaccess ?

[emoxam]

@CADViewer Ok. I am using this one now https://github.com/nextcloud/server/blob/master/.htaccess i added two strings, so it look like

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{HTTP_USER_AGENT} DavClnt
  RewriteCond %{REQUEST_FILENAME} !/apps/cadviewer/converter/php/.
  RewriteRule ^$ /remote.php/webdav/ [L,R=302]
  RewriteRule .* - [env=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
  RewriteRule ^\.well-known/carddav /remote.php/dav/ [R=301,L]
  RewriteRule ^\.well-known/caldav /remote.php/dav/ [R=301,L]
  RewriteRule ^remote/(.*) remote.php [QSA,L]
  RewriteRule ^(?:build|tests|config|lib|3rdparty|templates)/.* - [R=404,L]
  RewriteRule ^\.well-known/(?!acme-challenge|pki-validation) /index.php [QSA,L]
  RewriteRule ^ocm-provider/?$ index.php [QSA,L]
  RewriteRule ^(?:\.(?!well-known)|autotest|occ|issue|indie|db_|console).* - [R=404,L]
  RewriteRule . index.php [PT,E=PATH_INFO:$1]
</IfModule>

i do systemctl restart apache2

i refresh my nextcloud page and i see loading that never ends. md files don't opens too. if i commented

  RewriteCond %{REQUEST_FILENAME} !/apps/cadviewer/converter/php/.
  RewriteRule . index.php [PT,E=PATH_INFO:$1]

and restarted my apache al become good. Here's logs

call-Api_Conversion_log (2).txt nextcloud.integris.ru-1700824513149.log

[CADViewer]

so the log from nextcloud.integris.ru still does not contain any listing from cadviewer, so it's like you are not selecting any dwg files in the file manager, also the call-Api_Conversion_log.txt is an old trace, so you are not firing off any conversions. (which is clear because you have nothing in the nextcloud.integris.ru trace)

[emoxam]

@CADViewer Is it because of vesrions? i am using nextcloud 24.0.0 I've installed cadviewer 9.17.2 via the apps section.

Or it's because i am using nginx reverse proxy ?
