Ventoy Persistence has become discouraging. What have I done wrong.?

[Resistor]

I made a change and fixed empty lines and trailing spaces.



The menu shows Mint 20 and LMDE-4.

No persistence options indicated.



The file path looks proper.

Code:

/dev/sdb2  7D22-F13A
Mounted on /media/gt/VTOYEFI

Code:

/dev/sdb1  ventoy
Mounted on /mnt/gt/ventoy

Directory looks correct as the example suggested:

Code:

/mnt/gt/ventoy/ventoy/ventoy.json

Properties shows:

Code:

/mnt/gt/ventoy
/mnt/gt/ventoy/ventoy
/mnt/gt/ventoy/ventoy/ventoy.json

/mnt/gt/ventoy/linuxmint-20-cinnamon-64bit.iso
/mnt/gt/ventoy/persistence.img

/mnt/gt/ventoy/lmde-4-cinnamon-64bit.iso
/mnt/gt/ventoy/persistence.img

On re-boot, F5 gives a syntax error message.



I removed the space from the top line: #ventoy.json

I'll be back after a reboot with the current .json file:

Code:

#ventoy.json
{
    "persistence": [
        {
            "image": "/linuxmint-20-cinnamon-64bit.iso",
            "backend": "/persistence.img"
            "autosel": 1
        },
        {
            "image": "/lmde-4-cinnamon-64bit.iso",
            "backend": "/persistence.img",
        }
    ]
}

---

Just rebooted.
F5 shows an error message, more or less like this:

############## Syntax errors... ##############

That error message may be the same as before, but I can not say for sure.

So, where could the problem be?
