Getting Error: _setThrew is not defined when accessing parquet file #1966
Description
What happens?
Hi, I'm new to using DuckDB WASM, so I apologize if I'm missing something simple.
I'm using the WASM implementation in a Svelte application. I can correctly instantiate the DuckDB connection and register a file. However, when I try to execute a query I get the error Error: _setThrew is not defined.
The https file is CORS enabled, but the same error occurs when I try to read a local file. Trying to pass the Parquet file directly to "read_parquet", within the query, produces the same error.
I appreciate any help.
To Reproduce
Here is the full Svelte code that goes into +page.svelte
<script lang="ts">
import { onMount } from "svelte";
import * as duckdb from "@duckdb/duckdb-wasm";
import duckdbWasm from '@duckdb/duckdb-wasm/dist/duckdb-mvp.wasm?url';
import mvpWorker from '@duckdb/duckdb-wasm/dist/duckdb-browser-mvp.worker.js?url';
let db;
let connection;
let errorMsg = "";
onMount(async () => {
try {
const worker = new Worker(mvpWorker);
const logger = new duckdb.ConsoleLogger();
db = new duckdb.AsyncDuckDB(logger, worker);
await db.instantiate(duckdbWasm);
connection = await db.connect();
console.log("DuckDB connection established!");
// Connect to a remote file
await db.registerFileURL('remote.parquet', 'https://mpaeu-dist.s3.amazonaws.com/source/data/species/key=1003504.parquet');
console.log("File registered");
// UP HERE IS WORKING
// Run a query
// HERE IT IS FAILING
const query = "SELECT COUNT(*) AS count FROM read_parquet('remote.parquet')";
const result = await connection.query(query);
console.log("Query executed.")
console.log(result)
} catch (error) {
errorMsg = error.message;
console.error("Error initializing DuckDB:", errorMsg);
}
});
</script>
