ParseError

Represents an error that occurs when invalid JSON is received by the server, resulting in a parsing error.

This error is typically encountered when a JSON-RPC request is malformed or the JSON syntax is incorrect. It’s a standard JSON-RPC error with code -32700, indicating issues at the protocol level rather than the application level.

Example

try {
  await client.request({
    method: 'eth_getBalance',
    params: ['0x1234567890123456789012345678901234567890', 'latest'],
    // Imagine this request is somehow malformed JSON
  })
} catch (error) {
  if (error instanceof ParseError) {
    console.error('JSON-RPC parse error:', error.message);
    console.log('Check the request format and try again');
  }
}
