Apisix-dashboard: The route imported through Apisix's interface using Export OpenAPI exported file is empty

[wangruozhu]

Issue description

I want to synchronize old data, the old apisix version is 1.4.0, and now I use apisix with version 2.4 and apisix-dashboard with version 2.4, etcd with version v3.4.15.
I use Apisix's interface '/apisix/admin/route' to import my route data, I see it work by apisix-dashboard.
When I use Export OpenAPI to export this route data, the file which I export was empty.
But another route which I create by apisix-dashboard I can export full data to file.

Expected behavior

I want to export full json data to file using Export OpenAPI function.
The route data is imported by Apisix's interface and not only create by apisix-dashboard.

How to Reproduce

1、imported route data by Apisix's route api
2、find it on apisix-dashboard
3、choose this route, click Export OpenAPI to export json data
4、see this json file

• Thank you for your reply. I have located the problem.
• When the methods field data is empty or [], the route supports all methods, but the export does not do relevant adaptation. This is a bug, and I will fix it in the near future.
• The fastest way to solve this problem is to add the methods field corresponding to the route, such as "methods": ["DELETE"], to ensure that the methods data is not empty, which will not affect the use of the export function. Thks.

For example

$ curl http://127.0.0.1:9080/apisix/admin/upstreams/00000000000000000058 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -i -X PUT -d '
{"name":"UC-EUREKA", "desc": "UC-EUREKA", "enable_websocket": false, "hash_on": "vars", "nodes": {"172.16.0.123:18088": 1}, "type": "roundrobin", "methods": ["GET"]}'
