The error `unknown directive "client_header_buffer_size:"` indicates a
syntax issue in the NGINX configuration snippet. NGINX directives use
**spaces** as separators, not colons. For example:
```yaml
# ❌ Wrong (colon separator)
apisix:
nginx:
configurationSnippet:
httpSrv: |
client_header_buffer_size: 32k;
# ✅ Correct (space separator)
apisix:
nginx:
configurationSnippet:
httpSrv: |
client_header_buffer_size 32k;
```
The `configurationSnippet` values (values.yaml lines 454-466) are injected
directly into `nginx.conf`, so they must follow standard NGINX configuration
syntax.
Closing as this was a configuration syntax error. If you still have
questions, please feel free to reopen.
