Using the following launch.json, I’m able to hit breakpoints in the module level code, but not in route-handlers.

launch configuration (the last three lines may not be needed, but are just some things I’ve tried)

{
    "name": "Chalice: Local",
    "type": "python",
    "request": "launch",
    "program": "${workspaceFolder}/.venv/bin/chalice",
    "args": [
        "local",
        "--no-autoreload",
    ],
    "console": "integratedTerminal",
    "justMyCode": false,
    "subProcess": true,
    "gevent": true
}

app.py:

...
app = Chalice(app_name="something") # breakpoint here does hit
...

@app.route("/{cluster}", methods=["POST"])
def deploy_pods(cluster):
    print(cluster) # breakpoint here doesnt hit (but I can see the print happening)
