Troubleshooting
Limitations
- The catalog is not refreshed automatically. To update the list of table in the catalog,
DETACH
from the catalog andATTACH
again. - Reading tables with deletes is not yet supported.
Curl Request Fails
Problem
When trying to attach to an Iceberg REST Catalog endpoint, DuckDB returns the following error:
IO Error:
Curl Request to '/v1/oauth/tokens' failed with error: 'URL using bad/illegal format or missing URL'
Solution
Make sure that you have the latest Iceberg extension installed:
duckdb
FORCE INSTALL iceberg FROM core_nightly;
Exit DuckDB and start a new session:
duckdb
LOAD iceberg;
HTTP Error 403
Problem
When trying to list the tables in a remote-attached catalog, DuckDB returns the following error:
SHOW ALL TABLES;
Failed to query https://s3tables.us-east-2.amazonaws.com/iceberg/v1/arn:aws:s3tables:... http error 403 thrown.
Message: {"message":"The security token included in the request is invalid."}
Solution
Use the duckdb_secrets()
function to check whether DuckDB loaded the required credentials:
.mode line
FROM duckdb_secrets();
If you do not see your credentials, set them manually using the following secret:
CREATE SECRET (
TYPE s3,
KEY_ID '⟨YOUR_ACCESS_KEY_ID⟩',
SECRET '⟨YOUR_SECRET_ACCESS_KEY⟩',
REGION '⟨YOUR_DEFAULT_REGION⟩'
);
