Cannot reload after updating extension

[UdoW]

I cloned the master GIT repo and followed the build instructions for the browser app. Everything worked fine. I am under Windows 10.

I loaded localhost:3000 and opened the extensions view. Then I updated the marker extension and after reloading I got an empty black screen.

See attached screen shots and log.

@UdoW Thank you for the issue. Could you also look into the console and post errors from there, please?

[UdoW]

I added the log file. Where else can I find logging output?

[akosyakov]

In Chrome there is More Tools -> Developer Tools and then Console

Ok, I have to rebuild it again...

@UdoW thank you

In the Theia repo using the extension manager is not going to work for everything since published extensions are outdated compared to the local.

The issue is here that we don't catch cases when frontend bindings are not compatible and because of it cannot revert installation.

It also can be caused by #667

This issue still present if one builds an electron application with @next version.

Closing since the extension manager has been deprecated #4876
