I am getting an odd error when I've ran juju version 3.5.3: jhack sync -s ./src -s ./lib/charms/opensearch/ opensearch returns a KeyError: "applications" on: https://pastebin.ubuntu.com/p/GdnB37rK3Y/ The model is set as my default and the opensearch application does exist.

Rolling back to juju version 3.4.5 resolves the issue.

Also using Juju 3.4.5, I also created an empty model and ran the command above (so I could trigger the same KeyError as above). I can see the error message is more complete: https://pastebin.ubuntu.com/p/6rrGhk8qyq/. It does find more information about the model:

           status = {

uhm that's odd, indeed. It looks like it has issues running juju status. Was the model still being set up by any chance?

[PietroPasotti]

can you share the output of juju status --format json?

[PietroPasotti]

I suspect it may have been an issue of the command being run too soon after model creation or another similar glitch. Without a reproducer and more data I can't help. Can you also try from edge?

Hi @PietroPasotti I can reproduce with the following steps:

sudo snap install juju --channel=3.5/stable
juju bootstrap localhost

juju add-model test2
juju deploy ubuntu

jhack version: installed: 0.4.3.3.1 (395) 114MB -

This is the juju status:

$ juju status
Model  Controller           Cloud/Region         Version  SLA          Timestamp
test2  localhost-localhost  localhost/localhost  3.5.4    unsupported  19:11:21Z

Now, if I run jhack, here is the output error I get: https://pastebin.ubuntu.com/p/D9tf9kMBJd/

I am running that test in an AWS instance with Ubuntu 22.04

Refreshed to edge (0.4.4.0.2) and still seeing issues.
