Severity:
High
Description:
Use pubsub.publish(topic, payload) to send a message. If the message size exceeds 4MB, the transmission will fail. No option or config provided to control the maximum message size.
Steps to reproduce the error:
const fileBytes = new Uint8Array(await file.arrayBuffer());
const payload = new Uint8Array(1 + fileBytes.length);
payload[0] = 1;
payload.set(fileBytes, 1);
await this.libp2p!.services.pubsub.publish(topic, payload);
