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

Bases: RPCException

Indicates an error with an asset

type_code = 4

type_name = 'asset'

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

Bases: RPCException

Indicates the asset does not exist

type_code = 5

type_name = 'asset_not_found'

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

type_code = 2

type_name = 'auth'

type_code = 1

type_name = 'format'

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

Bases: RPCException

type_code = 3

type_name = 'job'

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

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 (Message | None) – The message to processes

• log_level – level to log the exception message on
