Syntax

public sealed class MirrorGrpcException : Exception, ISerializable

Remarks

Thrown by SubscribeTopicAsync(SubscribeTopicParams, Action<IMirrorGrpcContext>?) when the mirror node's gRPC stream terminates unexpectedly. Messages that were already delivered to the ChannelWriter<TopicMessage> before the fault are still valid — only the stream itself is broken.

Inspect Code to decide how to recover:

• Unavailable — the mirror node is temporarily down. Transient — retry after a delay, resuming from the last received TopicMessage.SequenceNumber.
• CommunicationError — a network-level gRPC failure. Transient — retry.
• TopicNotFound — the topic address does not exist. Permanent — verify the topic EntityId.
• InvalidTopicAddress — the address exists but is not a topic. Permanent.
