url过长时会报错404 Route Not Found

[caster-Q]

Description

直连上游访问没有问题，不会报错，url设置短一些访问也不会报错
代理的elasticsearch，当索引名特别多，url过长时会报错，是不是代码里面承载url的变量有长度限制？
修改了nginx参数 large_client_header_buffers 40 200k; 没有效果

Environment

• APISIX version (run apisix version): 3.2
• etcd version, if relevant (run curl http://127.0.0.1:9090/v1/server_info): 3.5.4
