Invalid Debug Adapter

[andrew-laughlin]

PHP version: 8.3 Xdebug version: 3.3 VS Code extension version: 1.34.0

Your launch.json:

    {
        "name": "Listen for Xdebug",
        "type": "php",
        "request": "launch",
        "port": 9003
    }

Xdebug php.ini config: [xdebug] zend_extension = /home/user/.config/Local/lightning-services/php-8.3.0+1/bin/linux/lib/php/extensions/no-debug-non-zts-20230831/xdebug.so xdebug.mode=debug,develop xdebug.client_port=9003 xdebug.start_with_request=yes xdebug.discover_client_host=yes

Xdebug logfile (from setting xdebug.log in php.ini): VS Code extension logfile (from setting "log": true in launch.json):

Code snippet to reproduce:

When stopping a debugging session (by clicking stop on the debug bar), the following is consistently displayed in the VSCode output window (with "Extension Host") selected.

Hi. Are you on linux or on mac?

Does this happen even if no debug session is established? By that I mean you start Listen for Xdebug and then click stop before any PHP script gets run.

It'd be really helpful if you could provide "log":true debug contents from the Debug Console.

Thanks for the quick response. I'm on Debian 11.

That's correct. If I start, then stop the debug session, the "Invalid Debug Adapter" error is shown twice in the output window. Below is the debug console output. In this session, there is 1 breakpoint set.

Thanks. I'll try to reproduce it. Also. Do you have any other php related vscode extensions installed?

Theres also an "extension bisect" process I'll ask you to do, if I can't reproduce the problem.

Best!

A little more about my setup. I'm working on a Wordpress plugin and using Local 8.2 (which includes Xdebug 3.3.0). For unit tests I've been using the Devsense PHP extension (v1.42.14626). I've disabled this extension for troubleshooting.

The only other installed extension are .NET related.

[zobo]

Devsense and this plugin are sadly incompatible and "strange things" happen. Does the error happen when Devsense is disabled?

[andrew-laughlin]

Yes, Devsense is disabled when the error occurs.

I can confirm this does happen. I tried it on my windows PC and there it does not, then I tried Remote SSH to my debian VM and there I see it. When I stop the debugger, I get two of these exceptions.

The exception seems to happen on the fronted tho (see the paths)

In any case, debugging seems to work. I'll try to poke around this and report it to the vscode team...

I'll close this, as VSCode team is still working on this, but does not seem to interfere much with the extension. A newer issue https://github.com/microsoft/vscode/issues/196948
