I'm try to connect to icberge reset catalog using duckdb 1.4 following this guide https://docs.lakefs.io/latest/integrations/iceberg/ (example duckdb). got this error

Copy code

D ATTACH 'lakefs' AS main_branch (
      TYPE iceberg,
      SECRET lakefs_credentials,
      -- notice the "/relative_to/.../" part:
      ENDPOINT 'https://.../relative_to/repo.main/api'
  );
Invalid Input Error:
CatalogConfig required property 'defaults' is missing

this error is mislead (https://github.com/duckdb/duckdb-iceberg/issues/297#issuecomment-2973232577) it seems the problem is with endpoint , but I can't understand what is the issue

@Amihay Gonen As discussed on Slack we will handle this through a support ticket

lakefs 1

a little late to the party, but if this helps - the schema should be in the form of

<repo>.<branch>,<namespace>

. so it should be:

Copy code

CREATE SCHEMA IF NOT EXISTS your_lakefs_repo.main_branch.aa;
