Error when creating document

[JayVii]

Whenever I create a Document, I get following error (also see attached screenshot):
"Failed to load the document. Please ensure the filetype is supported and not corrupted, and try again."

Error in journalctl -xe:

It appears as if a) the process can not read the empty template file properly or b) the file is not correctly initialized yet when the process tries to open it. I already tried to replace the empty template in my nextcloud richdocument/empty/templates/ folder, but to no avail. If the later is true, a workaround might be to implement a delay before opening the file (I could not find such config in loolwsd.xml)

If I re-open the exact same file seconds later, it starts up fine. and works as intentional.

Here my build-config:

set_online_regex='collabora/code-4.2.1'
lo_src_branch='distro/collabora/cp-6.2'
lo_src_tag='cp-6.2-5'
set_core_regex='cp-6.2$'
lool_src_branch='distro/collabora/code-4.2.0-4'
lool_src_tag='CODE-4.2.0-4'
lool_configure_opts='--with-lokit-path=/opt/libreoffice/include --disable-werror'
poco_version='1.9.4'

[DmDS]

same thing... CODE-4.2.3-2.
4.1.* does not have this problem

@DmDS

same thing... CODE-4.2.3-2.
4.1.* does not have this problem

I cannot find any tag in https://github.com/LibreOffice/online containing CODE-4.1, can you post your working settings? That way, I at least have a workaround for the time being

EDIT:

lool_src_branch='distro/collabora/collabora-online-4'

results in LOOLWSD 4.1.0, however the issue still persists. This did unfortunately not fix the issue.

[JayVii]

I tried with

lool_src_branch='distro/collabora/collabora-online-4-0'

Version LOOLWSD 4.0.11 (last commit 2 months ago), but the issue persists.

[DmDS]

Try this conf. the script will use default settings for lool (collabora-online-4). with this config files are created without errors.

lool_configure_opts='--disable-werror'
set_core_regex='cp-6.2'
lo_src_tag='cp-6.2-11'
lo_src_branch='distro/collabora/cp-6.2'
lool_forcebuild=true

[JayVii]

Indeed, rebuilding LO itself with your above settings fixed the issue. However, also LO 6.4.4 works fine in combination with loolwsd 4.1.0 (which did not work with older LO versions).

To me it looks like LO was the issue rather than LOOLWSD. I am closing the issue, as everything works as expected now. Thanks @DmDS!

current working setup:

lo_src_branch='distro/collabora/cp-6.4'
lool_src_branch='distro/collabora/collabora-online-4'
lool_configure_opts='--with-lokit-path=/opt/libreoffice/include --disable-werror'
poco_version='1.9.4'

[DmDS]

i got it working with 4.2.*
…/nextcloud/apps/richdocuments/lib/Controller/WopiController.php
need to comment this code (lines 213-218. app ver 3.7.0)

//** if ($wopi->hasTemplateId()) {
$templateUrl = ‘index.php/apps/richdocuments/wopi/template/’ . $wopi->getTemplateId() . ?access_token=’ . $wopi->getToken();
$templateUrl = $this->urlGenerator->getAbsoluteURL($templateUrl);
$response[‘TemplateSource’] = $templateUrl;
}*/

[JayVii]

I can confirm, this fixes the issue entirely on 4.2.*

Thanks! I'll go ahead and open an issue on https://github.com/nextcloud/richdocuments

I can't reproduce the issue.

• Richdocuments: 3.7.0
• Core: 6.2-14
• Online: 4.2.4-2

[DmDS]

I can't reproduce the issue.

do you use https?

[Ark74]

yep

I have installed collabora on ubuntu and on debian, changed the default locales, installed two nextcloud instances. (but did not try to change the locale). nothing helped. there was no error with http. with https I got in the logs: "Failed to load: file:///user/docs/GS5jKjq3a8CY05rA/test.docx, error: Unsupported URL <https:// domain/index.php/apps/richdocuments/wopi/template/433?access_token = b4xTyicfRdRAMQb0uQ08U89hEorDaFQf>: "type detection failed" and "Server certificate verification failed: issuer is not trusted".
Certificates made by let's encrypt. i configured reverse proxy on apache, ngnix, haproxy... I don’t know .. maybe there is a problem in the nextcloud locale and special characters... and
issue only with creating the new documents. with templates i guess...
