~/.soda/configuration.yml not automatically used

[janet-can]

Using soda-core-postgres, 3.0.0b4.
Python 3.9.2

I have created a configuration.yml file in my ~/.soda directory. If I try to use the following scan command that ought to implicitly find the file, it produces an error.

soda scan -d aws_postgres_retail checks.yml
Soda Core 3.0.0b4
No configuration file specified nor found on ~/.soda/configuration.yml
Unknown error while executing scan.
  | dictionary changed size during iteration
  | Stacktrace:
  | Traceback (most recent call last):

  |     for data_source_scan_cfg in self._sodacl_cfg.data_source_scan_cfgs.values():
  | RuntimeError: dictionary changed size during iteration

But if I explicitly identify the configuration.yml and path, it works just fine.

soda scan -d aws_postgres_retail -c ~/.soda/configuration.yml checks.yml
Soda Core 3.0.0b4

All is good. No failures. No warnings. No errors.
