# E2404

> Google PubSub target — Message too large

The encoded data exceeds PubSub's 10 MB message limit, or the data plus attributes, ordering
key, topic resource name, and protobuf framing exceeds the 10 MB publish-request limit.

**Fix** — split the row, shorten its attributes, or use a smaller route-level encoding.
