'Error occurred when fetching containers' message in Fedora 32 and podman 2.0.3

[rmarting]

In my previous laptop with Fedora 31 this extension worked successfully and it was very productive for me. However I installed on my new laptop with a fresh installation of Fedora 32 but it seems that something is not working on.

I created some containers using podman 2.0.3 but the extension always show me the same message 'Error occured when fetching containers'

I don't know how to see the logs from the gnome extension, I only did:

❯ sudo journalctl /usr/bin/gnome-shell | grep -i container Jul 24 11:34:12 localhost.localdomain gnome-shell[2530]: clutter_container_add_actor: assertion 'CLUTTER_IS_CONTAINER (container)' failed Jul 24 11:34:12 localhost.localdomain gnome-shell[2530]: clutter_container_add_actor: assertion 'CLUTTER_IS_CONTAINER (container)' failed Jul 24 11:34:12 localhost.localdomain gnome-shell[2530]: clutter_container_add_actor: assertion 'CLUTTER_IS_CONTAINER (container)' failed
but without relevant information.

Is it Fedora 32 supported for this extension? Do I need to do something else?

I dig into this issue, but I am not at JavaScript expert, but it seems that some cases are not covered from the containers json format document.

podman ps -a --format json output in my case is:

❯ podman ps -a --format json | jq

The PopupSubMenuMenuItem class at line 255 tries to manage some attributes missed in the output showed above:

• Status
• ID

I am guessing that some error is throwed there and then the menu is not updated successfully. I tried to test locally but it seems that I don't know how to do it successfully.

My environment is:

• GNOME version: 3.36.4
• podman: 2.0.3

Thanks for reporting.
The latest plugin version was working well but something in gnome changed. I'll upgrade my gnome-shell and let you know.

[rmarting]

I did some changes and now it is working on my local. I will create a PR with my changes. Basically the json schema is different.

I am testing right now.

@rgolangh This is the PR created with my minimal changes.

I am not an JavaScript expert, so maybe some changes could be improved.
