You or your administrator must have mis-configured your installation. By default there is no a-language-server-implementation spec shipped with this extension, but your system - as per your logs - contains it:

    traitlets.traitlets.TraitError: schema errors:
        1 is not one of [2]
    for:
    {'a-language-server-implementation': {'version': 1, 'argv': ['/absolute/path/to/a-language-server', '--stdio'], 'languages': ['a-language']}}

and it contains the spec defined for version 1 whereas the current jupyter-lsp requires version 2 (as the error message is trying to tell you).

It appears that someone copy-pasted the configuration example from https://jupyterlab-lsp.readthedocs.io/en/latest/Configuring.html#language-servers without replacing placeholders -
/absolute/path/to/a-language-server is just an example path, a-language is just placeholder for language name etc. This is not going to work.

You need to find out where the faulty configuration was placed and get it removed. Closing as this is not a bug in jupyter-lsp.

In future, please do not post the same issue in three different repositories (here, jupyterlab and notebook) - this is considered impolite as it forces maintainers of all these projects to spend time reading and analysing your question.
