Error Handling

You may recieve an error message from us if there is something wrong with your request or if something unexpected happens during streaming such as exceeded limits, buffer overflow, missed ping messages, or if the node is going away.

In some cases, your websocket connection will be closed by us after sending an error message.

Error messages have a general structure and may or may not contain traceId depending on who initiated them:

{
  "traceId":"8y64fs9",
  "t":"error-bad-request",
  "p": {
    "message": "The number of transferBytes has exceeded. Limit: ${tier.maxTransferBytes}."
  }
}
