Erro lab.create()

[nguyentheanhhnd]

I try run script:

server = Gns3Connector(url="http://localhost:3080")
lab = Project(name="check", connector=server)
try:
    lab.create()
    print("Project created successfully")
except ValueError as e:
    print(f"Error creating project: {e}")
print(server.projects_summary())
print(lab.status)

this is erro :
python3 vidu2.py
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Can you post the version of GNS3 you are using and the version of pydantic as well?

[nguyentheanhhnd]

I am currently using GNS3 version 2.2.44.1, Python 3.8.10, and Ubuntu 20.04.6 LTS.

[nguyentheanhhnd]

I'm also having difficulty with node creation and link creation. Do you have any examples for this? thank you

[davidban77]

Here is a link to the documentation for node creation: https://davidban77.github.io/gns3fy/user-guide/#node-creation

Link creation is just after it.

I had the same error, using 'pip install gns3fy' on Ubuntu 20.04.
A dirty hack is to get the newest version of 'gns3fy.py' from GitHub (either clone the repos or make a raw copy of the file).
Then overwrite the existing file (which seems to be /usr/local/lib/python3.8/dist-packages/gns3fy/gns3fy.py in your case).

This fixes the 'pydantic_initialised was unexpected' error.

The "proper" solution (according to the documentation) to install the cloned GitHub version is using 'poetry', but this doesn't seem to work with Python 3.8.

I had the opposite on Ubuntu 24.10...

pip install gns3fy

will install by default the latest version from pypi.org, which is 0.8.0

With this version the script was throwing out some error like

Failed to create project: 400: JSON schema error with API request '/v2/projects' and JSON data '{'name': 'Test01', '__pydantic_initialised__': True}': Additional properties are not allowed ('__pydantic_initialised__' was unexpected)

What I did was to uninstall the gns3fy and re-install by specifying the version 0.7.2 (which is oddly the last stable version on github)

pip install gns3fy==0.7.2

Same script worked without the above error.
