JsonException: Control character error, possibly incorrectly encoded

[NickMous]

Hiya there, I'm trying to set up a new project with deployer 8, and I'm getting a JsonException the whole time, without any useful information.
Can anyone help me debug this, if I'm the problem or the script is?

It's a fresh laravel application.

[<project-stag>] run cd /var/www/<project>/01 && (ln -nfs --relative releases/6 /var/www/<project>/01/release)
done on <project-stag>
  ⠼
In Server.php line 190:

  [JsonException (3)]
  Control character error, possibly incorrectly encoded

Did some more digging in Server.php, and it's not completely giving a correct array.
The code array_slice($lines, $i + 1), which is in the json_encode (imploded), does not result in a correct array. See example:

array (
  0 => '{
    "host": "<proj-stag>",
    "config": {
        "alias": "<proj-stag>",
        "hostname": "<host>",
        "remote_user": "deployer",
        "port": 1124,
        "deploy_path": "\\/var\\/www\\/<proj-stag>",
        "selected_hosts": [
            "<proj-stag>"
        ],
        "shell": "bash -ls",
        "env": [],
        "default_timeout": 300,
        "dotenv": false,
        "forward_agent": true,
        "ssh_multiplexing": true,
        "repository": "[email protected]:NickMous\\/<proj>",
        "what": "zcdb",
        "where": "zcdb01",
        "working_path": null,
        "current_path": "\\/var\\/www\\/<proj>\\/current",
        "user": "DDEV User",
        "releases_list": [
            "1"
        ],
        "release_name": "1",
        "branch": "HEAD",
        "target": "HEAD",
        "use_relative_symlink": true,
        "bin\\/symlink": "ln -nfs --relative"
  ',
)

No, I did not cut this off.

Found the issue! And it looks like it's not me...
In src\Executor\Server.php::readClientRequest() the socket is being read until we have 2 new lines.
Somehow in the socket there are two new lines, but it's not done reading.
I altered the code to output everything in separate files, and if people are interested I can provide it.
For now, I'm gonna create a bug issue and delve in it a bit deeper!

I encountered the same problem. On the Windows 10 platform, version 8.0.0-alpha.
