Hi @prusswan – thanks for opening this. Try loading the httpfs extension as well, this works around the problem for me:

LOAD httpfs;

Of course, the error message could be improved.

Still happens for me. I guess I will try with a more stable WASM version until this gets resolved.

I believe this to be solved in the latest duckdb/duckdb-wasm/spatial version.

Please check: https://shell.duckdb.org/#queries=v0,LOAD-spatial~,CREATE-TABLE-T-AS-FROM-ST_Read('https%3A%2F%2Fraw.githubusercontent.com%2Fibis%20project%2Ftesting%20data%2Fmaster%2Fgeojson%2Fzones.geojson')~,DESCRIBE-T~,SELECT-count(*)-FROM-T~

Or the equivalent SQL:

--- httpfs loading is necessary in native, while not working on wasm, we need to better align the two versions here
LOAD httpfs;
LOAD spatial;
CREATE TABLE T AS FROM ST_Read('https://raw.githubusercontent.com/ibis-project/testing-data/master/geojson/zones.geojson');
DESCRIBE T;
SELECT count(*) FROM T;
