Documented "basedirs" config file directive not recognized

[iskunk]

I am making use of the basedirs directive in the configuration file, exactly as described in the doc, yet sccache 0.13.0 fails to recognize it:

 0:27.08 error: process didn't exit successfully: `/usr/local/bin/sccache /bin/rustc-1.89 -vV` (exit status: 2)
 0:27.08 --- stderr
 0:27.08 sccache: error: Failed to load config file
 0:27.08 sccache: caused by: Failed to load toml config file from /etc/sccache.conf
 0:27.08 sccache: caused by: TOML parse error at line 4, column 1
 0:27.08   |
 0:27.08 4 | basedirs = ["/home/build"]
 0:27.08   | ^^^^^^^^
 0:27.08 unknown field `basedirs`, expected one of `cache`, `dist`, `server_startup_timeout_ms`

My config file looks like this:

basedirs = ["/home/build"]

[cache.disk]
dir = "/home/sccache"
size = 10737418240  # 10 GB

[cache.disk.preprocessor_cache_mode]
hash_working_directory = false

It is located at /etc/sccache.conf, and I am pointing SCCACHE_CONF to it.
