No response

I had the same issue in nextcloud AIO
Turned out this is not a server issue, it's an app issue caused by the app "htmlviewer" the app is not commonly used as such the low number of reports.

I believe this should be posted in the app repo instead.

Being curious, how did you find the source of this error since there are no further informations in the logs?

We opted not to use the app causing the error as we have other more secure ways to display html/php content (there is an app that allows you to display external links as iframe apps, as long as your remote server is secure and maintained by and you account from cross site vulnerabilities, it should be a safer way to go).

@ninjazan420 basic plugin/app troubleshooting, clear the log disable all apps and enabled one by one while checking the log with each activation, and isolate the app that triggers it

Alright, thank you very much :)

[devnoname120]

The culprit is in the htmlviewer app, file lib/Listeners/LoadViewerListener.php, line 53:

            Util::addScript('text', null, Application::APP_ID);

https://git.mdns.eu/nextcloud/htmlviewer/-/blob/ac29e6a7cfe867dea3c87afe37d89ac15e272151/lib/Listeners/LoadViewerListener.php#L53

Maybe it's just an oversight?

This is not an oversight, it's so i can force NC to load the app after mine and i can register a handler for html files.

[devnoname120]

@marius-wieschollek Pardon my ignorance but where can I Iearn more about the text app? I couldn't find a reference to it.

Being curious, how did you find the source of this error since there are no further informations in the logs?

I tried to see if I could enhance the logging this morning (to log the original app that registered the script). It doesn't look like we can log the original app in the ResourceLocator. The check (and associated logging) is too far along. All we have at that point is the path to the script.

This is not an oversight, it's so i can force NC to load the app after mine and i can register a handler for html files.

We have similar issues rich richdocuments and onlyoffice. One quick hack might be something like nextcloud/text#2448 (or even nextcloud/richdocuments#2301).

Maybe we can come up with a better way of prioritizing handler registration - e.g.

• by having some apps (like Viewer and Text) automatically defer to any other apps that are installed.
• by exposing the handling as a setting (in a consistent way rather than in each app) when there are multiple potential handlers available for a given type

Hmm... actually looks like we've got two Issues covering this area so let's move there:

nextcloud/viewer#2393
#5065
