InvalidArgument

InvalidArgument indicates client specified an invalid argument.

Note that this differs from FailedPrecondition. It indicates arguments

that are problematic regardless of the state of the system

(e.g., a malformed file name).

FieldTypeLabelDescription
field_violations InvalidArgument.FieldViolation repeated

Describes all violations in a client request.

InvalidArgument.FieldViolation

A message type used to describe a single invalid field.

FieldTypeLabelDescription
field string

A path leading to a field in the request body. The value will be a sequence of dot-separated identifiers that identify a protocol buffer field. E.g., "field_violations.field" would identify this field.

description string

A description of why the request element is bad.

Empty

A generic empty message that you can re-use to avoid defining duplicated

empty messages in your APIs. A typical example is to use it as the request

or the response type of an API method. For instance:

service Foo {

rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);

}

The JSON representation for `Empty` is empty JSON object `{}`.
