Received an invalid response from the server

Error message

Received an invalid response from the server: {0}

What it means

This Error variant is InvalidResponse(#[from] FieldViolation) with the message "Received an invalid response from the server: {0}". It is raised when a response message from the IOx server fails client-side proto validation — a required or well-formed-expected field is missing or violates its constraint, surfaced as a prost FieldViolation. Unlike the Status-mapped variants, it originates in the client's decoding/validation path rather than from a server status code.

Solutions

1. Check for a version mismatch between influxdb_iox_client and the server and align versions.
2. Log the FieldViolation details (field path and description) to identify which field failed validation.
3. Remove or bypass any intermediary proxy that may alter gRPC payloads.
4. If reproducible on matched versions, file a bug against the server with the failing RPC and payload shape.

Example fix

// before: treating all errors the same
let resp = client.query(req).await?;
// after: inspect the FieldViolation to find the offending field
match client.query(req).await {
    Err(Error::InvalidResponse(violation)) => {
        eprintln!("bad field '{}' : {}", violation.field, violation.description);
        // check client/server version skew
    }
    other => /* ... */,
}

// assert matched versions to reduce proto skew
assert_eq!(client.server_version().await?, EXPECTED_SERVER_VERSION);

fn is_invalid_response(e: &client::Error) -> Option<&prost_types::FieldViolation> {
    match e {
        client::Error::InvalidResponse(v) => Some(v),
        _ => None,
    }
}

match res {
    Err(Error::InvalidResponse(v)) => {
        log::warn!("field '{}' invalid: {}", v.field, v.description);
        // check version skew, then decide whether to fail or degrade
    }
    other => other.map_err(Into::into),
}

When it happens

Trigger: Server (or an intermediary) returns a response message missing a required field; a field value violates its proto validation rule during conversion into the client's types via #[from] FieldViolation.

Common situations: Client and server proto definitions out of sync after a version skew upgrade; a buggy or custom proxy rewriting responses; server bug emitting a partial message for an edge-case result.

Understand the failure class

Background: "invalid response format", "malformed payload", "missing data field": when an API returns 200 but the response shape is wrong — this error's family across 23 libraries.
