after testing, online demo site still return 500 on debug page.
so if the online site updated automaticly, would you please provide a way to view the log， or last update log here? many thanks😊 @nic-chen

and I also have a question , the api /apisix/admin/routes/:rid/debuginfo which is added to get route details with Apisix url (because fe has to send the debug request directly to apisix，so I need the apisix url here) works well in my Local docker environment， but got 500 in online demo site, maybe it is caused by configuration( we did not consider enough when analyzing the parameters),so would you please provide apisixBaseUrl config in the demo site, thanks again~!

@liuxiran
base_url is:
http://apisix-admin-svc:9080/apisix/admin

I think we should judge the value of res before using it :
https://github.com/apache/apisix-dashboard/blob/master/api/route/route.go#L535

online debug page is Available ，but the debug request still failed.

• reason
  After communicating with @nic-chen , The online site is a network environment where the internal and external networks are isolated. This would also be a common deployment strategy.
  At present, the baseURl got by reading conf.json is an intranet address and cannot be used for online debug

• solution
  try to add a config item in the conf.json, which used to configure debugUrl, that would fix the https://github.com/apache/apisix-dashboard/blob/69199d22dd30e47a71c191060a0402d43633addf/src/pages/Route/transform.ts#L353 together

@liuxiran, after the incoming fix, does it support mock server?

cc @moonming Could you please leave your question or confusion here?

[liuxiran]

@liuxiran, after the incoming fix, does it support mock server?

the debug requires Apisix to forward the request to the corresponding upstream, it would support mock server only when mock server can complete this forwarding job :)

[juzhiyuan]

got it, tks!
