Excluding Sample App Info breaks the browser

[jonrhuang]

Starting from working with the example browser, I tried removing unused dependencies from the package.json. I found that removing "@theia/api-samples" would pretty much break the ide's visuals. After a little more digging in the examples/api-samples directory I found that removing the SampleAppInfo specifically was the cause. I'm very new to Theia but I don't understand what in the sample app info would cause this or how to fix it

Hey @jonrhuang,

if you're not familiar with the framework, I would recommend you to start off with the yeoman generator for Theia. It builds a ready-to-use app that you can extend without trying to modify already existing code.

[jonrhuang]

Can you try it from commit 0dcdcd4... tag: v1.63.0, Author: Simon Graband. This is where I have been working from.

[msujew]

I checked out the commit, still works as expected for me. Can you provide some error logs perhaps from the application? Since you're running on 1.63.0 directly, you might be hitting #15901, which was fixed in 1.63.1.

[jonrhuang]

The app is still able to launch. It is however, unusable. The only error message is that a .theia/backend-settings.json does not exist, but I don't recall that being an issue before.

What shows on my browser:

The terminal still works, I can switch to the problems tab, and the outline icon on the right will open a window when clicked.

How I reproduced:

1. git clone https://github.com/eclipse-theia/theia.git && cd theia
2. git checkout 0dcdcd4d398f4106746d0f701205abdb668383f3
3. Delete every dependency except @theia/{core, editor, filesystem, markers, messages, monaco, navigator, plugin-ext-vscode, preferences, process, terminal, workspace} all on 1.63.0 from examples/browser/package.json
4. Run npm i && npm run build:browser && npm run start:browser

I mean browser logs. Given that your app essentially looks like in the referenced issue, I assume you're hitting the same bug. Please use v1.63.1 instead.

Thank you, that has fixed the issue
