Getting `Uncaught Error: Table type not specified` when integrating in a nextjs project

[saikatmitra91]

What happens?

I just installed duckdb-wasm in my next js project and tried importing JSON.

I keep getting Uncaught Error: Table type not specified

I saw it's not loading JSON extension wasm file at all.
when I use a similar query on shell.duckdb.org, it works ! and JSON extension file is downloaded too.

I might be missing something here.

Please recommend what I need to do in order to mitigate the issue

Can you try issue an explicit "LOAD json" on the conn object after this line: const conn = await db.connect(); ?

Is the error referring to an Arrow Table that DuckDB connections returns results in? Do you need to add the dependency for the apache-arrow package?
