Heimdall not recognized anymore since updating WUD from 8.3.0 to 8.3.1

[bcutter]

After updating WUD from 8.3.0 to 8.3.1, the container Heimdall is not recognized anymore. It is missing in the WUD web UI and also not provided via API anymore as a Home Assistant sensor confirms:

Applying

       --label wud.watch.digest=true \
       --label wud.watch=true \

to the heimdall container docker run command made no difference.

Full docker run command:

sudo docker run -d \
       --name=heimdall \
       --restart=always \
       -e PUID=1000 \
       -e PGID=1000 \
       -e TZ=Europe/Berlin \
       -p xxx.xxx.xxx.xx:80:80 \
       -v /opt/heimdall/config:/config \
       --label wud.watch.digest=true \
       --label wud.watch=true \
       lscr.io/linuxserver/heimdall:2.8.1

I checked https://github.com/getwud/wud/releases/tag/8.3.1 but could not spot anything directly related to this as a root cause.

Once I downgrade WUD to v8.3.0, Heimdall shows up again:

What about this?

Update: switched from lscr.io/linuxserver/heimdall:2.8.1 to linuxserver/heimdall:2.8.1 and Heimdall now shows up again with latest WUD v8.3.1. BUT: now it shows an update - which is impossible and very old:

What the...?

[bcutter]

Spending/Wasting another 30 minutes (AI summary):

WUD still shows phantom update for linuxserver/heimdall:2.8.1

WUD continues to report a non‑existent update (2021.11.28) for the image linuxserver/heimdall:2.8.1, even when:

• wud.registry=docker.io is set
• wud.watchdigest=false is set
• Docker Hub is the only intended registry
• The image tag is fully pinned and unchanged

Observed WUD-side issues:

• WUD ignores the user-defined registry and still queries upstream registries referenced in the OCI annotations (lscr.io, ghcr.io).
• WUD detects tags that do not exist on the selected registry (phantom tag 2021.11.28).
• Disabling digest watching does not prevent cross‑registry tag comparison.
• lscr.io is only partially supported, causing mismatched digests and false update signals.

Expected behavior:
WUD should respect wud.registry=docker.io and avoid reporting tags that do not exist on that registry.

Did you try clicking "watch now" again? I have seen a container missing, right after updating, so I think that certainly is an issue.

While using LSCR, did you configure the registry as the documentation says? I haven't been using lscr yet, but it is documented you need to setup a registry: https://getwud.github.io/wud/#/configuration/registries/lscr/

In docker hub there is a container called 2021.11.28, WUD sees version 2021.11.28 as newer than 2.8.1 as semver wise this is true (2021 > 2), so this isn't really a bug.
I suspect this tag does not exist on lscr and that is why it's not being shown.

You can use wud.tag.include as a way to include only semver with 1-3 numbers in front and not years (I suspect they never get to 1000 versions) wud.tag.include=^\d{1,3}\.\d+\.\d+$ see also Include only 3 digits semver tags

Did you try clicking "watch now" again?

Of course...

Now I went through providing a token for LSCR using https://getwud.github.io/wud/#/configuration/registries/lscr/ and switched back to using lscr.io/linuxserver/heimdall:2.8.1 again, but now still...

Oh dear why the hell needs this stuff to be that complicated.

Using your specific --label 'wud.tag.include=^\d{1,3}\.\d+\.\d+$' \ was working (the original one from https://getwud.github.io/wud/#/configuration/watchers/?id=include-only-3-digits-semver-tags was not).

So I guess I don't really need the LSCR token anymore but I can switch from lscr.io/linuxserver/heimdall:2.8.1 to linuxserver/heimdall:2.8.1 again, as this was not working - only the tag include filter does.
