"Error 500: [Errno 2] No such file or directory: "YANG set '...' owned by '...' (609 modules)"

[8bitDesigner]

Hi all, I just checked out this project this morning, and I'm receiving the following error when trying to explore a yangset I have set up:

Error 500: [Errno 2] No such file or directory: "YANG set 'ms390-default-yangset' owned by 'pausween' (609 modules)"

And the stack trace from the console:

Steps to reproduce

1. Start a clean install of yangsuite on MacOS 13.2.1:

$ ~/.pyenv/versions/3.8.12/bin/python -m venv yangsuitevenv
$ source yangsuiteenv/bin/activate
$ pip install pip wheel setuptools --upgrade
$ pip install yangsuite
$ yangsuite

2. Set up a new device profile under "Setup > Device Profiles"
3. Select the profile, and click "Create default Repository and Yangset"
4. Go to "Explore > YANG", select the newly configured yangset, select a module, and click "Load module(s)"

I'm not a Python expert, but I think this is because the YSContext class is being inited with a YSYangSet instead of a string, which would explain why the error message is printing out "No such file or directory: '{YSYangSet string representation}'". If I replace the YSYangSet's string representation method with yangset_path(self.owner, self.setname) (eg: print its path instead of a description), this seems to work

i'm having the same issue. can you give more detail on what files and lines you changed to work around this?

In my case it was yangsuitevenv/lib/python3.8/site-packages/ysfilemanager/filemanager/yangset.py where yangsuitevenv is the name of the virtualenv I set up to install YangSuite into

We have a bug open on this, the engineer was able to reproduce it, and we should have a fix soon.

Hi, I'm having a similiar issue. Yang repos and module sets can be configured, but trying to open any model for exploration in the Explore -> YANG tab errors out with Error 500: 'YSContext' object has no attribute 'repository'

The server logs:

A fix for this has been deployed to yangsuite-yangtree as a pre-release. Pre-releases can be manually installed or you can wait for yangsuite-yangtree 2.1.3 main release (probably sometime next week).

** NOTE: your directory or container name may vary depending on your install

source yangsuite/venv/bin/activate
pip install --upgrade --pre yangsuite-yangtree

For docker containers first enter the container using the exec command.

docker exec -it yangsuite bash
pip install --upgrade --pre yangsuite-yangtree

Should have yangsuite-yangtree 2.1.3.post0.dev3 showing in Admin-->Manage plugins
