Running Reflex via systemd stopped working after v.0.6.2

[givaha]

Describe the bug
Running Reflex via systemd service stopped working after v.0.6.2.
I create a .sh-script that the systemd service uses to keep reflex running (see steps to reproduce)
The steps to reproeduce the issue work on version 0.6.2.

To Reproduce
Steps to reproduce the behavior:

# Create virtual environment
python3 -m venv venv
source venv/bin/activate

# Install Reflex (0.6.7, latest version)
pip3 install reflex 

# Create Reflex project (blanco)
reflex init 
0

# Create a bash 'service_startup.sh' script with this content + give execute rights (sudo chmod +x service_startup.sh)
source /home/user/folder/venv/bin/activate
reflex run --loglevel debug --frontend-port 3001 --backend-port 8001

# Create a systemd service (reflex.service in /etc/systemd/system)
[Unit]
Description=Reflex App
After=network.target

[Service]
WorkingDirectory=/home/user/folder
ExecStart=/home/user/folder/service_startup.sh
Restart=always

[Install]
WantedBy=multi-user.target

# Start the service
**sudo** systemctl start reflex.service

This will give error:

You can add a command like this:

ExecStartPre=/home/lendemor/.virtualenvs/mywebsite/bin/reflex init

Which will preemptively run reflex init like the error message is asking you to.
