Max nodes reached (128)

[billybob83400]

Dear All,

Sorry to reopen this topic but I cannot find any relevant answer.
I explain: I am using API (postman) to manage my fresh new lab and try to create a new node (just one).
Desipte status success I cannot create nodes via API, I receive this message:
{
"code": 201,
"status": "success",
"message": "Max nodes reached ( 128 )",
"data": {
"id": 1
}
}

Here is the body I'm trying to post:
{
"type":"qemu",
"template":"Linux",
"config":"Unconfigured",
"delay":0,
"icon":"Server.png",
"image":"linux-ubuntu-mate-20.04",
"name":"Kube-Node-",
"left":"35%",
"top":"25%",
"ram":"4096",
"console":"vnc",
"cpu":2,
"ethernet":1
}

Here is the lab details:
{
"code": 200,
"status": "success",
"message": "Lab has been loaded (60020).",
"data": {
"author": "admin",
"description": "A new test lab with API",
"body": "Lab usage and guide",
"filename": "LABtest.unl",
"name": "LABtest",
"version": "1",
"scripttimeout": 600,
"lock": 0
}
}
I am well authenticated as admin, there is no other user using eve-ng.

my disk space is ok:
$ df -h
Filesystem Size Used Avail Use% Mounted on
udev 7.8G 0 7.8G 0% /dev
tmpfs 1.6G 18M 1.6G 2% /run
/dev/mapper/eveng--vg-root 109G 34G 70G 33% /
tmpfs 7.8G 0 7.8G 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock

/dev/sda1 720M 244M 440M 36% /boot
tmpfs 1.6G 0 1.6G 0% /run/user/1000

Any Idea of what could cause the limit to be reach via API ?
Moreover, I am totally able to create new node via WebUI.
Thanks to all of you
