TypeError: Cannot read properties of null (reading 'concat')

I was getting issue with sub-subcommand:

[Extension Host] [Completion] No completion item is available (1) TypeError: Cannot read properties of null (reading 'concat')
	at getOptions (/Users/vsaboulin/.vscode/extensions/tetradresearch.vscode-h2o-0.2.12/out/extension.js:558:40)
	at getCompletionsOptions (/Users/vsaboulin/.vscode/extensions/tetradresearch.vscode-h2o-0.2.12/out/extension.js:524:21)
	at Object.<anonymous> (/Users/vsaboulin/.vscode/extensions/tetradresearch.vscode-h2o-0.2.12/out/extension.js:66:47)
	at Generator.next (<anonymous>)
	at fulfilled (/Users/vsaboulin/.vscode/extensions/tetradresearch.vscode-h2o-0.2.12/out/extension.js:5:58)

I fixed it by changing:

const options = deepestCmd.options.concat(...inheritedOptionsArray);

to

const options = (!!deepestCmd && !!deepestCmd.options) ? deepestCmd.options.concat(...inheritedOptionsArray) : [];

It's probably not the best code, but that seems to work in my case

Thank you so much for your report and the fix!
I've added it, and published as 0.2.13.

Works perfectly now !
