   > > @Ben0625 Could you try the `2.5` version? And test it whether it can be reproduced in `2.5`?
   > 
   > I tried the Apisix 2.5 version but not use the dashboard 2.5 version. I just connect to the same etcd and it can be reproduced. Let me provide more details. Step 1. Set a route with two upstreams(/test.do) and healthcheck active configuration(/check.do) through dashboard. Step 2. Send a request to trigger creating new checker. By looking at the log output before and after to_set() function:
   >

   > > {
   > > 1 = 429,
   > > 2 = 500,
   > > 3 = 503,
   > > }
   > > defaults.checks.passive.unhealthy.http_statuses after to_set() function:
   > > {
   > > 429 = true,
   > > 500 = true,
   > > 503 = true,
   > > }
   > 
   > Step 3. Edit the same route on dashboard and do not change any configuration and commit. Step 4. Send a request to trigger creating new checker. By looking at the log output before and after to_set() function:

   -------------------------
   
   Following the steps you provided, I tested it through the CLI and Dashboard in the APISIX2.8 version, and this problem was not reproduced.
