vscode launch.json files

[robertblackwell]

HI, Looking for help with vscode launch files in order use a pico debug probe (not a second pico).
I am working on a Ubuntu 22.04 host, have openocd setup and can use gdb-multiarch to debug a blink program on a pico.
When I try to use the launch files provided in pico-examples/ide/vscode vscode complains that:

        "type":"cortex-debug",

"please use node type instead", and for these :
"executable": "${command:cmake.launchTargetPath}",
"servertype": "external",
"gdbPath" : "gdb-multiarch",
"gdbTarget": "localhost:3333",
"svdFile": "${env:PICO_SDK_PATH}/src/rp2040/hardware_regs/rp2040.svd",
"runToEntryPoint": "main",
// Work around for stopping at main on restart
"postRestartCommands": [
"break main",
"continue"
]

each of these lines have a key words that are "not allowed". I am obviously missing something that will turn out to be obvious. But I cannot see it.
