Problem loading ducklake extension

General Usage
1

When trying to load the ducklake extension in DuckDB v1.3.1 I get the following error:

ERROR: Execute of query "LOAD ducklake;" failed: HTTP Error: Failed to download extension "ducklake" at URL "http://extensions.duckdb.org/v1.3.1/x86_64-w64-mingw32/ducklake.duckdb_extension.gz" (HTTP 403)
Extension "ducklake" is an existing extension.
=ducklake
Stacktrace:

Code:

using DuckDB
using DBInterface
using DataFrames

file_name = "duck data.db"
db = DuckDB.DB(file_name)
conn = DBInterface.connect(db)
try
    df = DuckDB.query(db,"SELECT version() as duckdb_version;") |> DataFrame
    show(df)
    DBInterface.execute(conn, "LOAD ducklake;")
finally
    close(conn)
    DBInterface.close!(db)
end

Program output:

1×1 DataFrame
 Row │ duckdb_version 
     │ String
─────┼────────────────
   1 │ v1.3.1

When running duckdb CLI, the extension is loaded successfully and functions normally.

Any thoughts on what is going wrong and how I can fix it?
Thank you

Oh looks like it is related to the bug I encountered just the other day. If you scroll down to my comment, I link to a potential fix there: duckdb.jl: installing extensions on linux pulls inexistent url · Issue #17743 · duckdb/duckdb · GitHub
