gxthrj opened a new issue #5908: URL: https://github.com/apache/apisix/issues/5908
### Issue description To determine that a header does not exist, you need to use `null`, it works like: ``` curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' { "uri": "/ip", "upstream": { "type": "roundrobin", "nodes": { "httpbin.org": 1 } }, "vars": [["http_hello", "==", null]] }' ``` But using nil will not work, it will report an error: ``` curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d ' { "uri": "/ip", "upstream": { "type": "roundrobin", "nodes": { "httpbin.org": 1 } }, "vars": [["http_hello", "==", nil]] }' ``` errors：{"req_body":"\n{\n \"uri\": \"\/ip\",\n \"upstream\": {\n \"type\": \"roundrobin\",\n \"nodes\": {\n \"httpbin.org\": 1\n }\n },\n \"vars\": [[\"http_hello\", \"==\", nil]]\n}","error_msg":"invalid request body: Expected value but found invalid token at character 169"} ### Environment - apisix version (cmd: `apisix version`): 2.10 - OS (cmd: `uname -a`): centos7 - OpenResty / Nginx version (cmd: `nginx -V` or `openresty -V`): - etcd version, if have (cmd: run `curl http://127.0.0.1:9090/v1/server_info` to get the info from server-info API): - apisix-dashboard version, if have: - the plugin runner version, if the issue is about a plugin runner (cmd: depended on the kind of runner): - luarocks version, if the issue is about installation (cmd: `luarocks --version`): -- This is an automated message from the Apache Git Service.
