Your question

Greetings! I seek your expertise to assist in resolving an error in execution.py:

def execution_block_cb(block): if block.message is not None: mes = { "prompt_id": prompt_id, "node_id": unique_id, "node_type": class_type, "executed": list(executed),

                    "exception_message": f"Execution Blocked: {block.message}",
                    "exception_type": "ExecutionBlocked",
                    "traceback": [],
                    "current_inputs": [],
                    "current_outputs": [],
                }
                server.send_sync("execution_error", mes, server.client_id)
                return ExecutionBlocker(None)
            else:
                return block
