QProcess setEnvirontment fails

[nkpatro]

Hi
I am working on a application launcher and using QProcess to Launch the application. However, QProcess is failing to set the environment.
The application launches without a license.

Here is the version of code.

void MainWindow::appItemClicked(const QString &appName)
{
    QJsonObject jo = getApplicationInfo(appName);
    auto joEnv = jo.value(QString("env")).toObject();
    auto joBin = jo.value(QString("bin")).toArray();
 
    QStringList args;
    foreach (auto val, joBin)
        args << val.toString();
 
    auto env = QProcess::systemEnvironment();
    foreach (auto key, joEnv.keys())
    {
         auto newValue = joEnv.value(key).toString();
         env.insert(key, newValue);
     }
    QProcess process;
    process.setProgram(args[0]);
    args.pop_front();
    if (args.count() > 0)
        process.setArguments(args);
    process.setProcessEnvironment(env);
    process.startDetached();
    process.waitForFinished(-1);
}

void MainWindow::appItemClicked(const QString &appName)
{
    QJsonObject jo = getApplicationInfo(appName);
    auto joEnv = jo.value(QString("env")).toObject();
    auto joBin = jo.value(QString("bin")).toArray();

    QStringList args;
    foreach (auto val, joBin)
        args << val.toString();

    auto env = QProcess::systemEnvironment();
    foreach (auto key, joEnv.keys())
    {
         auto newValue = joEnv.value(key).toString();
         env.insert(key, newValue);
     }
    QProcess process;
    process.setProgram(args[0]);
    args.pop_front();
    if (args.count() > 0)
        process.setArguments(args);
    process.setProcessEnvironment(env);
    process.startDetached();
    process.waitForFinished(-1);
}

getApplicationInfo () returns this data

{
  "env": {
    "FOUNDRY_LOG_FILE": "/Scratch/log/nuke/nuke11.log",
    "RLM_LICENSE": "port@ip_address",
  },
  "bin": [
    "/usr/local/Nuke11/Nuke",
    "--nukex"
  ]
}

{
  "env": {
    "FOUNDRY_LOG_FILE": "/Scratch/log/nuke/nuke11.log",
    "RLM_LICENSE": "port@ip_address",
  },
  "bin": [
    "/usr/local/Nuke11/Nuke",
    "--nukex"
  ]
}

If I run the same in "/bin/bash" the application finds the license and works perfectly.
the shell script looks like this

#!/bin/bash
 
export FOUNDRY_LOG_FILE=~/software/Scratch/log/nuke/nuke11.log
export RLM_LICENSE=port@ip_address
 
/usr/local/Nuke11/Nuke --nukex

#!/bin/bash

export FOUNDRY_LOG_FILE=~/software/Scratch/log/nuke/nuke11.log
export RLM_LICENSE=port@ip_address

/usr/local/Nuke11/Nuke --nukex

Can anyone help find where am I going wrong?

Thanks in advance.
