http error

Error message

http error: {0}

What it means

A variant of influxdb3_server::Error wrapping a boxed http::Error (the http crate's builder error) via #[from]. It indicates a failure constructing an HTTP request or response — e.g. an invalid URI, header value, or method — at the http layer, before hyper sends it.

Solutions

1. Check the inner http::Error message for which component (URI, header, method) was invalid
2. Ensure any programmatically built URIs/headers are properly percent-encoded and contain only valid ASCII header values
3. If caused by a client-supplied URL, fix the request URL and retry

Example fix

// before
let req = http::Request::builder()
    .uri(user_input_url) // may be invalid
    .body(body)?;
// after
let url = user_input_url.parse::<http::Uri>()
    .map_err(|e| format!("invalid url: {e}"))?;
let req = http::Request::builder()
    .uri(url)
    .body(body)?;

if let Err(e) = url.parse::<http::Uri>() {
    return Err(format!("invalid request URL: {e}"));
}
for (k, v) in &headers {
    http::HeaderValue::from_str(v).map_err(|e| format!("bad header {k}: {e}"))?;
}

When it happens

Trigger: Building an HTTP request/response with an invalid URI or illegal header value inside the server; code paths that convert an http::Request/Response and the http crate rejects malformed components.

Common situations: Programmatically constructed requests containing non-ASCII or control characters in headers; invalid percent-encoding in query paths; bugs in server request-building code surfaced to callers.

Understand the failure class

Background: "Invalid URL" errors: why new URL(), URI.parse, and reqwest::Url reject your string — missing scheme, whitespace, and bad path format — this error's family across 39 libraries.
