Exception

The momotor.rpc.exception module contains exception classes and a function to convert RPC messages with an exception field into a Python exception.

exception momotor.rpc.exception.RPCException(text, wire_message=None)

Bases: Exception

Base class for all protocol exceptions.

When a subclass of RPCException is raised by an RPC method, the exception is caught and converted into a Message containing the exception’s type_code and text

Should not be raised directly, but use one of the subclasses.

Parameters

  • text – textual explanation of the exception

  • wire_message – the Exception message to include in the RPC response

type_code = 0
type_name = 'rpc'
property wire_message
exception momotor.rpc.exception.FormatException(text, wire_message=None)

Bases: momotor.rpc.exception.RPCException

Indicates an invalid (combination of) arguments

type_code = 1
type_name = 'format'
exception momotor.rpc.exception.AuthException(text, wire_message=None)

Bases: momotor.rpc.exception.RPCException

Indicates an authentication error

type_code = 2
type_name = 'auth'
exception momotor.rpc.exception.JobException(text, wire_message=None)

Bases: momotor.rpc.exception.RPCException

Indicates an error with the job

type_code = 3
type_name = 'job'
exception momotor.rpc.exception.AssetException(text, wire_message=None)

Bases: momotor.rpc.exception.RPCException

Indicates an error with an asset

type_code = 4
type_name = 'asset'
exception momotor.rpc.exception.AssetNotFoundException(text, wire_message=None)

Bases: momotor.rpc.exception.RPCException

Indicates the asset does not exist

type_code = 5
type_name = 'asset_not_found'
momotor.rpc.exception.raise_message_exception(message, *, log_level=10)

If the message has an exception field, convert it into an RPCException and raise it

If message is None, raises UnexpectedEndOfStream.

If message has an exception field set, raises a subclass of RPCException

Produces logging information on the momotor.rpc.exception logger

Parameters

  • message (Optional[Message]) – The message to processes

  • log_level – level to log the exception message on
