Theia: MDK vscode extension is not deployed properly

[DoroNahari]

Description

MDK vscode extension is not deployed properly on theia.

Reproduction Steps

I try to use MDK vscode extension on theia (latest\next)
https://marketplace.visualstudio.com/items?itemName=SAPSE.vsc-extension-mdk

On theia: run command: Deploy plugin by ID -> Insert the plugin id: vscode:extension/SAPSE.vsc-extension-mdk

I can see that the plugin is deployed but the plugin features are not available.
Issues for example:

• There should be MDK commands added to the commands (not found with F1).
• There should be a new MDK terminal.
• There should be MDK preferences.
• The MDK language is loaded but no auto-completion, validation, navigation, etc.

OS and Theia version:
Windows/Mac, theia (latest\next)

Diagnostics:
mdk-logs-server.txt
mdk-logs-client.txt

If you can provide a link to source code for this extension it would be nice. I could not find it on marketplace page. It would help with detailed analysis.

@DoroNahari
deploying the vsix I have the menu entries

or preferences

I see in your log a trace about some modules not found that I haven't

oot ERROR [hosted-plugin: 247] { Error: Cannot find module 'vscode-json-languageservice/lib/umd/services/JSONSchemaService.js'
    at Function.Module._resolveFilename (module.js:548:15)
    at Function.Module._load (module.js:475:25)
    at Function.module._load (/home/theia/node_modules/@theia/plugin-ext-vscode/lib/node/plugin-vscode-init.js:83:33)

maybe issue is in docker build

ok so from what I've found is that your extension is loading 'vscode-json-languageservice/lib/umd/services/JSONSchemaService.js'

at Object.<anonymous> (/tmp/vscode-unpacked/SAPSE.vsc-extension-mdk-1.6.1.vsix/extension/node_modules/mdk-languageservice/lib/service/schema/SchemaService.js:10:25

let JSONSchemaService = require('vscode-json-languageservice/lib/umd/services/JSONSchemaService.js').JSONSchemaService;
class MDKSchemaService extends JSONSchemaService {

but looking at the files:

$ ls -la node_modules/vscode-json-languageservice/lib/umd/services/
total 140
drwxr-xr-x 2 theia theia  4096 Apr 17 00:39 .

-rw-r--r-- 1 theia theia  6501 Apr 17 00:39 jsonValidation.js

the files don't have the same lowercase/uppercase so I would say it's only working on non case-sensitive filesystems (like myself with macOS)

you should fix your code

Thanks, the case-sensitive fix solves the deployment problem.
