If I have Scrapy 2.13.2 installed ScrapyRT fails to respond to REST API requests. For example, if we launch it on quotesbot project and try accessing http://127.0.0.1:9080/crawl.json?url=http://quotes.toscrape.com/&spider_name=toscrape-xpath the request will time out, but ScrapyRT logs the following:

2025-06-23 14:10:47+0000 [scrapyrt] Created request for spider toscrape-xpath with url http://quotes.toscrape.com/ and kwargs {}

This also happens with a larger Scrapy project I am developing.

Quick experimentation shows that Scrapy version 2.12.0 was last release when ScrapyRT still worked and something in 2.13.0 seem to have broken it.
