To provide context on why you are now seeing this error, is that with v1.0.0, we've decided to show vim extension errors as these alerts so that it would be easier for users to identify errors when vscodevim is misconfigured (ie. remappings, neovim) or when things are not working as expected. We've always logged it to the console, but this wasn't very discoverable. The related configurations are below if you would like to go back to the old behaviour of living in bliss/ignorance of these errors 😅 :

Setting	Description	Type	Default Value
vim.debug.suppress	Boolean indicating whether log messages will be suppressed.	Boolean	false
vim.debug.loggingLevelForConsole	Maximum level of messages to log to console. Logs are visible in the developer tools. Supported values: 'error', 'warn', 'info', 'verbose', 'debug').	String	error
vim.debug.loggingLevelForAlert	Maximum level of messages to present as VS Code information window. Supported values: 'error', 'warn', 'info', 'verbose', 'debug').	String	error

Now, in terms of this particular error, what were the series of keypresses that you did to generate this error?

[kenorb]

I don't know what keypresses I used, noticed the error after a while. If this happen again, I'll update.
