Hi @zhangyuxiang11356-code! I'm Dosu and I’m helping the RSSHub team.

The bug is in line 43 of lib/routes/digitalpolicyalert/activity-tracker.ts:

const items: DataItem[] = response.results.slice(0, limit).map((item): DataItem => {

The code assumes the API at https://api.globaltradealert.org/dpa/intervention always returns a results array, but response.results is undefined—likely due to an API change or error response.

Fix: Add validation before calling .slice():

const items: DataItem[] = (response.results ?? []).slice(0, limit).map((item): DataItem => {

This would return an empty feed instead of crashing when the API doesn't return the expected structure.

To reply, just mention @dosu.
