Cannot set env without running a program.

[mccaig]

Hi - I'm unable to launch the debugger - I receive the error that was mentioned in #788 (Cannot set env without running a program. Please remove env from [Listen for Xdebug] configuration.)

Note that I do not have an env variable set in my launch config - see below.

VS Code extension version: 1.29.0
Your launch.json:

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

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

I edited the extension source to print the contents of args.env in the error message:
throw new Error(Cannot set env without running a program.\nPlease remove envs: ${JSON.stringify(args.env)} from [${args.name || 'unknown'}] configuration.);
You can see in the debugging output that env is an empty object - as the extension is testing for args.env !== undefined it is failing the test.
I'm not sure if there was a change to the extension or even VSCode itself that is causing this variable to now be an empty object, or whether there is something weird about my IDE setup, but I don't see any obvious issues.

<- launchResponse
Response {
  seq: 0,
  type: 'response',
  request_seq: 2,
  command: 'launch',
  success: false,
  message:
   'Cannot set env without running a program.\nPlease remove env [{}] from [Listen for Xdebug] configuration.',
  body:
   { error:
      { id: 0,
        format:
         'Cannot set env without running a program.\nPlease remove env [{}] from [Listen for Xdebug] configuration.',
        showUser: true } } }

Perhaps this error might be better off as a warning?

Interesting. What is the vscode version?

[Keanu73]

Hi, I am also experiencing this exact same issue. My VSCode version is 1.74.0, and the extension version is v1.29.0.

[Keanu73]

I've made a fix for this, see my PR #872

[zobo]

Thanks. So weird that it never happens to me. Will look at the PR

[zobo]

Quite curious, I still cannot reproduce the issue. Do you have any other PHP related extensions installed?

[Keanu73]

The only other PHP-related extension I have installed is PHP Intelephense, nothing else.

[zobo]

Could you try to disable all other extensions? I will release a version (hopefully today) with this fix, but I'd like to take this up with Microsoft if it turns out that vscode is doing this.

[zobo]

Alternatively, I think there is a Help>Report option where you can also generate a list of all active extensions.

I've installed 1.29.1 and can confirm the bug is no longer present.

I went over the most extensions that would make sense but could not find any registerDebugConfigurationProvider that could cause this... I will close the issue. I would make sense to bisect the problem with the old version of the php-debug adapter, but honestly I can't spare the time...

Thanks for all the help!
