Error class
The error class indicates how you should handle the error:
Error class
Transient
The publish request has failed due to a temporary condition. You can
retry the process.
Examples:
Publishing quota has been met.
An internal Eventarc error has occurred.
Fatal
Publishing this event can't succeed and can't be retried in its
current form. Depending on the specific error, you can try altering or
restructuring the event to correct the error, and then retry the publish
request.
Examples:
The event is malformed, or contains invalid input.
The publish request contains too many events.
Fatal Channel
The subscriber's channel can't be published to; either it no longer
exists, or has become permanently disabled. This request can't be retried
and you should stop all event publishing. You can safely delete thechannelConnectionresource.
Examples:
The subscriber has deleted the connected channel.
The subscriber has deleted the Pub/Sub transport
topic for the channel.
