Solutions

Set all four FANFOU_* env vars and restart.
Remove the route from clients if fanfou is not used.

Example fix

# before
# (partial or no fanfou config)
# after
FANFOU_CONSUMER_KEY=...
FANFOU_CONSUMER_SECRET=...
FANFOU_USERNAME=...
FANFOU_PASSWORD=...

Defensive patterns

Strategy: validation

Validate before calling

const f = config.fanfou;
const ok = f && f.consumer_key && f.consumer_secret && f.username && f.password;
if (!ok) throw new Error('Fanfou RSS is disabled ...');

Type guard

const isFanfouConfigured = (c: any): boolean =>
  !!c?.fanfou?.consumer_key && !!c?.fanfou?.consumer_secret &&
  !!c?.fanfou?.username && !!c?.fanfou?.password;

Prevention

Set all four FANFOU_* vars together.
Centralize the fanfou config guard in utils to avoid drift across routes.

When it happens

Trigger: Any of the four FANFOU_* env vars is unset when /fanfou/user-timeline/:uid is requested.

Common situations: Optional fanfou config omitted, partial, or renamed during deploy.
