400 Request Header Or Cookie Too Large

[francoeder]

Description

I'm in my first steps with Apache APISIX.
I just followed the step by step contained in this page apisix-workshop, promoted by Bobur Umurzokov.

What did I do:

• I ran the containers using the docker-compose command (following what the tutorial guides)
• I created a route to an api that I already have published
• I created an upstream
• I edited the created route to consider the created upstream

However, when invoking a GET request for the mapped route, I get the error "400 Request Header Or Cookie Too Large".
curl -i -X GET "http://127.0.0.1:9080/api/v1/conteudos"

Can anyone help me?

Environment

• APISIX version (run apisix version): 2.13.1
• Operating system (run uname -a): Windows
• OpenResty / Nginx version (run openresty -V or nginx -V): ???
• etcd version, if relevant (run curl http://127.0.0.1:9090/v1/server_info): 3.4.15
• APISIX Dashboard version, if relevant: 2.10.1
• Plugin runner version, for issues related to plugin runners: -
• LuaRocks version, for installation issues (run luarocks --version): -

@francoeder Can you paste the exact route and upstream configuration that you have configured? Also share the logs from access.log and error.log, if any.

The requested information is below.

Route configuration

{
  "uri": "/api/v1/conteudos",
  "name": "api-conteudos-dev",
  "methods": [
    "GET",
    "POST",
    "PUT",
    "DELETE",
    "PATCH",
    "HEAD",
    "OPTIONS",
    "CONNECT",
    "TRACE"
  ],
  "plugins": {
    "redirect": {
      "http_to_https": true
    }
  },
  "upstream_id": "469405594722239177",
  "status": 1
}

Upstream configuration

{
  "nodes": {
    "nest-apiconteudosdev.onrender.com": 1
  },
  "timeout": {
    "connect": 10,
    "send": 10,
    "read": 10
  },
  "type": "roundrobin",
  "scheme": "http",
  "pass_host": "pass",
  "name": "api-conteudos-dev",
  "keepalive_pool": {
    "idle_timeout": 60,
    "requests": 1000,
    "size": 320
  }
}

Note: The access.log and error.log files show nothing different after executing the offending request (curl -i -X GET "http://127.0.0.1:9080/api/v1/conteudos").

Thanks in advance for the help!

I managed to solve the problem.

This thread helped me 👉 #6296

I needed to configure a proxy-rewrite plugin in my route, considering the domain of my API (Same domain used in the upstream) and Voilà! I was able to consume my API via APISIX Api Gateway.

I hope it helps someone in the future.

@francoeder You can close this issue. Thanks

Because APISIX uses nginx under the hood, i solved it by adding this to my config.yml

nginx_config:
  http_server_configuration_snippet: |
    large_client_header_buffers 4 32k;
