Limit to on urls sitemap json

I'm trying to import a JSON sitemap in chrome extension as always but doesn´t work for more than 399 urls when previously worked for 9999. Website to scrape it's amazon.es

@garralva Hi, can you show what type of an error is displayed after you are trying to import the sitemap?

Alternatively, this post might be helpful - Is it possible to have more than one input url in the same sitmap?

Solved, the error came because one quotation mark inside of one of the urls to scrape.

but when i try to uplaod it does not uplaod the sitemap?
