## Attaching to HTTPS Databases in v1.5.2

DuckDB v1.5.2 has a known issue where opening an HTTPS database directly from the command line fails with an error during httpfs extension autoloading:

```bash
duckdb https://blobs.duckdb.org/data/tpch-sf1.db
```

```console
Extension Autoloading Error:
An error occurred while trying to automatically install the required extension 'httpfs':
Initialization function "httpfs_duckdb_cpp_init" from file ".../.duckdb/extensions/v1.5.2/osx_arm64/httpfs.duckdb_extension" threw an exception:
"Schema with name main does not exist!"
```

To work around this, prefix the URL with `duckdb:`:

```bash
duckdb duckdb:https://blobs.duckdb.org/data/tpch-sf1.db
```

## Piped Scripts Not Running in v1.5.0

On Linux and macOS, DuckDB v1.5.0 has a known issue that the [command line client]({% link docs/current/clients/cli/overview.md %}) does not interpret piped scripts ([#21243](https://github.com/duckdb/duckdb/issues/21243)).

To demonstrate the problem, create a `test.sql` file:

```bash
echo "SELECT 42 AS x;" > test.sql
```

Piping the file to the DuckDB 1.5.0 CLI client does not run the script:

```bash
duckdb < test.sql
# does not run the script
```

To work around this, add `| cat` to the end of the call:

```bash
duckdb < test.sql | cat
```

```text
┌───────┐
│   x   │
│ int32 │
├───────┤
│    42 │
└───────┘
```

If you are piping from a file, you can also use the [`-f` argument]({% link docs/current/clients/cli/arguments.md %}):

```bash
duckdb -f test.sql
```

```text
┌───────┐
│   x   │
│ int32 │
├───────┤
│    42 │
└───────┘
```
