…alid (#7668)
The `otel` exporter example in `docs/config.md` is misleading and will
cause
the configuration parser to fail if copied verbatim.
Summary
-------
The example uses a TOML inline table but spreads the inline-table braces
across multiple lines. TOML inline tables must be contained on a single
line
(`key = { a = 1, b = 2 }`); placing newlines inside the braces triggers
a
parse error in most TOML parsers and prevents Codex from starting.
Reproduction
------------
1. Paste the snippet below into `~/.codex/config.toml` (or your project
config).
2. Run `codex` (or the command that loads the config).
3. The process will fail to start with a TOML parse error similar to:
```text
Error loading config.toml: TOML parse error at line 55, column 27
|
55 | exporter = { otlp-http = {
| ^
newlines are unsupported in inline tables, expected nothing
```
Problematic snippet (as currently shown in the docs)
---------------------------------------------------
```toml
[otel]
exporter = { otlp-http = {
endpoint = "https://otel.example.com/v1/logs",
protocol = "binary",
headers = { "x-otlp-api-key" = "${OTLP_TOKEN}" }
}}
```
Recommended fixes
------------------
```toml
[otel.exporter."otlp-http"]
endpoint = "https://otel.example.com/v1/logs"
protocol = "binary"
[otel.exporter."otlp-http".headers]
"x-otlp-api-key" = "${OTLP_TOKEN}"
```
Or, keep an inline table but write it on one line (valid but less
readable):
```toml
[otel]
exporter = { "otlp-http" = { endpoint = "https://otel.example.com/v1/logs", protocol = "binary", headers = { "x-otlp-api-key" = "${OTLP_TOKEN}" } } }
```
