query error

Error message

query error: {0}

What it means

This variant wraps QueryExecutorError, raised by the query executor that mediates between the HTTP layer and the write/query engine. It indicates the query could not be planned or executed at the executor level — distinct from raw DataFusion failures — such as unknown databases or executor-side validation failures.

Solutions

1. Confirm the database name in the `db` query parameter exists on this server.
2. Read the inner QueryExecutorError message for the executor-level cause.
3. Create the database or write at least one point before querying it.
4. Check server logs for catalog/executor problems if the database demonstrably exists.

Example fix

// before
curl 'http://localhost:8181/query?db=prod_db' --data-urlencode 'q=SELECT * FROM cpu'
// after
# verify the database exists first, then use the exact name
curl 'http://localhost:8181/query?db=prod-db' --data-urlencode 'q=SELECT * FROM cpu'

// verify the database exists before querying
const dbs = await fetch(`${host}/api/v3/config/databases`);
if (!dbs.includes(db)) throw new Error(`database ${db} does not exist`);

try { await execQuery(db, q); } catch (e) { if (e.message.startsWith('query error: ')) console.error('executor rejected query:', e.message); throw e; }

When it happens

Trigger: Sending a query to /query or /api/v3/query_* where the executor rejects it: the database does not exist, the namespace cannot be resolved, or the executor fails preparing the statement.

Common situations: Querying a database (bucket) name that was never created or was deleted; wrong db parameter casing; querying a server in a state where the catalog has not loaded the database.

Understand the failure class
