"""Firebase Exceptions module.
This module defines the base types for exceptions and the platform-wide error codes as outlined in
https://cloud.google.com/apis/design/errors.
:class:`FirebaseError` is the parent class of all exceptions raised by the Admin SDK. It contains
the ``code``, ``http_response`` and ``cause`` properties common to all Firebase exception types.
Each exception also carries a message that outlines what went wrong. This can be logged for
audit or debugging purposes.
When calling an Admin SDK API, developers can catch the parent ``FirebaseError`` and
inspect its ``code`` to implement fine-grained error handling. Alternatively, developers can
catch one or more subtypes of ``FirebaseError``. Under normal conditions, any given API can raise
only a small subset of the available exception subtypes. However, the SDK also exposes rare error
conditions like connection timeouts and other I/O errors as instances of ``FirebaseError``.
Therefore it is always a good idea to have a handler specified for ``FirebaseError``, after all the
subtype error handlers.

INVALID_ARGUMENT = 'INVALID_ARGUMENT'
