Node js, fs - does not save the file after executing all queues during long work, why?

Question

JavaScript

I am making a site parser, there is a list of links to products.
Parsing works through the async/queue queue , if you give the parser 200 pages, then the parsing ends normally, and at the end the data file is saved normally, and if you give 1200 pages (all), then the parsing passes, but the data file is not created at all. What could be the problem, and how can I track it through debugging?

Code from the page parsing file

ps - если это гавнокод и где-то можно было сделать лучше, прошу напишите - мне это будет полезно
