I get same error in custom plugin when rewrite upstream.
Upstream data:
```json
{
"id": "ups-sys1-abcd",
"create_time": 1643165083,
"update_time": 1643190928,
"nodes": [
{
"host": "example.com",
"port": 80,
"weight": 1
}
],
"type": "roundrobin",
"hash_on": "vars",
"scheme": "http",
"pass_host": "pass",
"name": "ups-sys1-abcd"
}
```
Route:
```json
{
"id": "1",
"create_time": 1643186095,
"update_time": 1643187397,
"uri": "/get",
"name": "",
"methods": [
"GET"
],
"host": "sys1.com",
"plugins": {
"custom-plugin": {}
},
"upstream": {
"nodes": [
{
"host": "httpbin.org",
"port": 80,
"weight": 1
}
],
"type": "roundrobin",
"hash_on": "vars",
"scheme": "http",
"pass_host": "pass"
},
"status": 1
}
```
Custom plugin code:
```lua
function _M.rewrite(conf, ctx)
-- rewrite by request header
-- get upstream info
local upstreams = core.config.fetch_created_obj("/upstreams")
if not upstreams then
return core.response.exit(502)
end
-- new upstream id by system name and tag
local upstream_id = "ups-sys1-abcd"
local ups_info = upstreams:get(tostring(upstream_id))
if not ups_info then
return
end
ups_info = ups_info.value
upstream.set(ctx, ups_info.name, ctx.conf_version, ups_info)
end
```
error log:
```
