Azure DevOps Custom Task Extension: powershell.exe / node.exe exit code: 5

I have PowerShell Script as a custom task inside a Build pipeline. The steps of these tasks are:

1. Checkout a repositroy branch
2. Compile a solution in these branch
3. Copy the checkout and the compiling results to a server inside the network

(because of some legacy stuff I can't compile the solution on the server directly)

To make these task more handsome, I wrap this PowerShell Script inside a custom build task.

The index.ts looks like:

import tl = require('azure-pipelines-task-lib/task');

async function run() {
    try {
        //PARAMETERS
        var params: string[] = ['Major', 'Minor', 'Work', 'Share', 'RepositoryUri', 'Branch', 'ProjectConfig', 'Include', 'Exclude'];
        var required: boolean[] = [true, true, true, true, false, false, false, true, false];
        var paramList: string[] = [];

        //LOOP ALL PARAMETERS
        for (let i = 0; i < params.length; i++) {
            var item: string = tl.getInput(params[i], required[i]) || '';
            if (item != null && item != '') paramList.push('-' + params[i] + ' ' + item.replace(/(?:\r\n|\r|\n)/g, ','));
        }

        //START CHILD PROCESS
        var spawn = require('child_process').spawn, child;
        console.log('##[command][js] call: powershell.exe ' + __dirname + '/DeployGit.ps1 ' + paramList.join(' '))
        child = spawn('powershell.exe', [__dirname + '/DeployGit.ps1 ' + paramList.join(' ')]);

        //REDIRECT CONSOLE OUTPUT
        child.stdout.on('data', function (data: string) { console.log(data.toString()); });
        child.stderr.on('data', function (data: string) { console.log(data.toString()); });
        child.on('exit', function (code: number) { console.log('##[command][js] powershell exit code:', code); process.exit(code) });
        child.stdin.end(); //END INPUT
    }
    catch (err) { tl.setResult(tl.TaskResult.Failed, err.message); process.exit(-1) }
}

run();

So the only job of this custom task is to call the PowerShell script.

The Problem

If I execute the PowerShell script with a PowerShell Buildpipeline Task, everything is fine. The Task takes about 20 min, but every thing works.

If I execute the wrapped custom task the task throw an error after ~11-12 min in the 3. phase of the task (Copy the checkout and the compiling results to a server inside the network)

The Error Message

##[section]Abschließen: Task: DeployGit.ps1

My interpretation of the error message is that node.exe thorws an error with the exit code 5.

In this article windows use error code 5 for Access is denied. But it more feeling like node.exe can't handle the long copy process for any reason.

Conclusion

I used the custom wrapped tasks in many cases and it is the first time that I have a problem, maybe it is relatet to the long execution time?

I'am sorry for the long and the very specific problem, I only hoped that some other developer run into a similar situation, cause I have no idea what is going on here.
