Describe the bug
Request connection/TestConnectionRequest failed with message: Cannot convert undefined or null to object

To Reproduce

1. Trying open any .sqlite3 and test connection
2. After save of connection the Unable to write into workspace settings. Please open the workspace settings to correct errors/warnings in the file and try again. - we often need use this tool in django, but file is used...so connections settings should offer save profile in any case of failed test

What happens if you try to update workspace settings manually?
This is a VSCode error. VScode is unable to save settings in your workspace.

Since we completely rely on VSCode settings API and it looks like a file permissions error, I'll close it for now. But please, keep me updated.

If you have any suggestions on how to do this, let me know.

When trying change in profile then
You need to fix some issues in your machine first. Check the notifications on bottom-right before moving forward.
When trying select the profile of connection then I see on notification:
You need to install sqlite3@4.0.8 to connect test source: sqltools...
When trying install by "install now" then:

Failed to install dependencies for SQLite: Request DependencyInstaller/install failed with message: 
You need to install node@6 or newer and npm first to install dependencies. Install it and restart to continue.

Just checking, did you enable setting "sqltools.useNodeRuntime": true, as in https://vscode-sqltools.mteixeira.dev/driver/sqlite#1-prerequisites?

Check here an working example: https://github.com/mtxr/vscode-sqltools/blob/master/.test-database/project.code-workspace#L31

I see you have node 10.11.0 installed, so it's probably just a matter of enabling node binary.

[ManPython]

"sqltools.useNodeRuntime": true, exist.
But I not instaled node manualy or not do anything with this env. I belive that VSC do this or this ext. Should I do here something? There is no instruction or information that is required to do.

Looks that problems exist with sqlite. The test with mysql was ok. HVR I uninstaled this ext due that not speending my needs - I expect some option to write scripts, save these as files in dir and run if required to see data.
