bakerLecter opened a new issue, #9777: URL: https://github.com/apache/apisix/issues/9777
### Current Behavior Enable Plugin in config and use it restrict some route in dashboard. Because there is no default config sample in dashboard when setting the workflow plugin. So I copy this https://apisix.apache.org/zh/docs/apisix/3.0/plugins/workflow sample to the dashboard and modified it as I expected as below. ``` // I know it's wrong now. "workflow": { "_meta": { "disable": false }, "actions": [ [ "return", { "code": 500 } ] ], "case": [ [ "uri", "==", "/v1/kv.*" ] ] } ``` After I update this route to apisix, etcd problem pop out at once. `52#52: *1281175 [lua] config_etcd.lua:595: failed to fetch data from etcd: /usr/local/apisix/apisix/plugins/workflow.lua:118: bad argument #1 to 'ipairs' (table expected, got nil)` And the route I just add is not available, any new route adding or modified is not working. I remove the plugin from the route and it still working abnormal, but the old routes and plugins are working fine. After I remove the workflow plugin from the route and reboot the apisix, things getting back to normal. ### Expected Behavior Apisix should warn me for the wrong config in dashboard. And it should back to normal after I remove the wrong config for plugin workflow without rebooting the whole apisix. ### Error Logs 46#46: *112327 [lua] config_etcd.lua:595: failed to fetch data from etcd: /usr/local/apisix//deps/share/lua/5.1/resty/expr/v1.lua:260: bad argument #1 to 'str_upper' (string expected, got nil) 47#47: *112276 [lua] config_etcd.lua:595: failed to fetch data from etcd: /usr/local/apisix//deps/share/lua/5.1/resty/expr/v1.lua:260: bad argument #1 to 'str_upper' (string expected, got nil) 52#52: *112001 [lua] config_etcd.lua:595: failed to fetch data from etcd: /usr/local/apisix//deps/share/lua/5.1/resty/expr/v1.lua:260: bad argument #1 to 'str_upper' (string expected, got nil) ### Steps to Reproduce 1. Run APISIX(version 3.0.0) with plugin workflow enable 2. Run APISIX Dashboard(version 3.0.1) 3. Adding or modify any route with plugin workflow via dashboard 4. make sure the configuration of plugin workflow is wrong 5. etcd problem should pop up now and any route modified will be failure but without any warning in dashboard ### Environment - APISIX version (run `apisix version`): version 3.0.0 - Operating system (run `uname -a`):Linux adminapisixgw-6ffb98cb69-5xj9d 4.19.0-10-amd64 #1 SMP Debian 4.19.132-1 (2020-07-24) x86_64 GNU/Linux - OpenResty / Nginx version (run `openresty -V` or `nginx -V`):nginx version: openresty/1.21.4.1 - APISIX Dashboard version, if relevant: version 3.0.1 - Plugin runner version, for issues related to plugin runners: apisix plguin - LuaRocks version, for installation issues (run `luarocks --version`): not showing -- This is an automated message from the Apache Git Service.
