Notifications fail if no "title url" set and cannot set title url to "$series.metadata.links[i].url"

Open vodkapmp opened this issue 7 months ago • 2 comments

When configuring notifications in the komelia webui, if I don't set a title url, I get the following error:

When I try and set the title to $series.metadata.links[i].url which is the only url that to me makes sense to set it to I get this:

Setting it to an actual plaintext url like google.com works just fine.

There's a bug in notification settings where if you've set the title url template before, you can't remove it You'll need to manually remove thetitle_url.vm template file in discord directory. That directory should be in the same directory as komf jar file or in config volume that you mount in docker.

Also i in the template context is the index of an array, for example if you know there's at least one link it'll be $series.metadata.links[0].url otherwise you can iterate through links in a loop

#foreach ($link in $series.metadata.links)
${link.url}
#end

That directory should be in the same directory as komf jar file or in config volume that you mount in docker.

Doing this changes nothing, same error message when a notification is triggered if the URL field is blank. (deleted file and restarted the docker container)

Also i in the template context is the index of an array, for example if you know there's at least one link it'll be $series.metadata.links[0].url otherwise you can iterate through links in a loop

Setting this to 0 for example, or 1 etc for that matter causes the same error as leaving the title_url field blank: io.ktor.client.plugins.ClientRequestException: Client request(POST https://discord.com/api/webhooks/REDACTED/REDACTED) invalid: 400 . Text: "{"embeds": ["0"]}"
