I have a short url website with over 700.000 shorts urls in it. I have created sitemaps for these short urls which i have uploaded to Google Search Console. the short urls looks like the examples bellow and every short url looks like this. This is a niche site which only redirect to one specific site. The problem is that when i look in google Search Console i get a lot of "pages with errors". when i check these urls every url with an error exists and is active.
Why am i getting error from the sitemaps and how can i remove them / get them to get indexed properly ?
Short url example
