<![CDATA[Unable to delete custom app - Docker error]]>Hello,
I attempted to install Zulip as a custom app. It didn't work, however I can't remove the app from the app page (or CLI) due to the error below. I'm getting certificate renewal errors every day.
Any suggestions appreciated.

Are you able to send us an email at support@cloudron.io and we can take a look. Should be something minor.

Seems very generic to me. As indicated above, there's no zulip image in docker images.

Not sure where this is coming from since the subdomain from the logs seems to be zulip. Can you make out what images might be referring to?

]]>https://forum.cloudron.io/post/31473https://forum.cloudron.io/post/31473Tue, 18 May 2021 05:27:49 GMT<![CDATA[Reply to Unable to delete custom app - Docker error on Mon, 17 May 2021 21:29:55 GMT]]>@girish Thanks for that. I commented out the line in docker.js

        if (error) {
            debug('Error removing image %s : %j', dockerImage, error);
//            return callback(new BoxError(BoxError.DOCKER_ERROR, error));
        }

Upon attempting to uninstall again, this is the error I get:

This happens because the docker image specified has incorrect syntax/malformed. I reported this upstream a while ago but it looks like docker returns a 301 code when it is supposed to return a 400 (!).

Can you try this:

        if (error) {
            debug('Error removing image %s : %j', dockerImage, error);
//            return callback(new BoxError(BoxError.DOCKER_ERROR, error)); <-- comment out this line
        }
  • Then , try uninstalling (no need to restart anything).

The command would be something like docker image rm <imageId>

Unfortunately that didn't help. The server has also been rebooted several times since first trying to uninstall.
