Cause

The JSON sent is not a valid JSON-RPC 2.0 Request object — e.g. missing `jsonrpc`/`method`, wrong types, or a malformed batch element.

Solution

  1. Include `"jsonrpc": "2.0"`, a string `method`, and an `id`.
  2. Ensure `params` is an array or object.
  3. Validate each element of a batch independently.

Example

{
  "id": null,
  "error": {
    "code": -32600,
    "message": "Invalid request"
  },
  "jsonrpc": "2.0"
}
