My application is a product book that will work offline. So I have a process that requests for a REST API all products, in this case, there are 6500 products. Each product has two images that total 13000 images.
In my function (fetchProducts) to get the products, I’m paging the data, so on each page I have 24 products. For each product I store the two image URLs of the product and then send it to my function (downloadFileMultiple) that will download the images
downloadFileMultiple
As the API pagination process is fast, several function calls (downloadFileMultiple) are executed, that is, for each page of 24 products, downloadFileMultiple are executed 24 times and so it will end up to 258 pages.
The problem occurs almost at the beginning, where the expo throws an exception with the problem below:

How could I do to solve this problem?
