Due to my mistake, I find myself with node-red inaccessible.  
This is what happens:

```auto

```

I found a reference to the function indicated in the log in the lrhome.json file:

```auto
  {
        "id": "865c2eb3.95e9b",
        "type": "function",
        "z": "a46ce386.b7383",
        "name": "",
(...)
"wires": [
            [
                "1305eeb0.a16011",
                "d9ae59d4.cab1d8"
            ]
        ]
    },

```

I tried to:

- delete the included function, the one that generates the infinite loop
- replace the json file
- reboot the system

I was hoping to be able to recompile node red from the web, but it wasn't possible.

I replaced the json file with one from a few days ago. No changes.

Do you have a suggestion to get out of this impasse, excluding a Colt or a slipknot? 🙂

If you restart Node-RED with the `--safe` command-line argument then it will load your flows without starting them. You can then edit them to remove the offending node(s) and hit deploy to start things up.
