load config %s except:%r

Error message

load config %s except:%r

What it means

get_config_value() tries to json.load a service config file (e.g. data/smart_router/config.json) and read a key; on any error it logs this warning and returns default_value — a soft fallback, not a crash.

Solutions

1. Check the printed file path exists and is valid JSON (python -m json.tool).
2. Delete/recreate the file and let the service regenerate it.
3. Fix permissions on the data directory.
4. Accept the default value if the service hasn't initialized yet.

import json, os
def read_conf(fn, key, default):
    try:
        with open(fn) as f: return json.load(f).get(key, default)
    except Exception: return default

try:
    value = json.load(open(fn)).get(key, default)
except (OSError, ValueError):
    value = default  # file missing or corrupt; service will regenerate

When it happens

Trigger: The JSON file is missing, empty, unreadable, or malformed; get_service_ports then falls back to defaults like 8086.

Common situations: First run before smart_router wrote its config; config corrupted by a crash mid-write; permission problems on the data dir.
