Hi, sometimes when I try to make api call, like download products: GET /wp-json/wc/v3/products?per_page=100&page=28

I get error 502 bad gateway

sometimes GET 1-30 pages return all fine, but sometimes (2-3rd run) I've got 502 bad gateway error

502 error generally happens when it takes a very long time to compute an API response. This is likely a generic performance issue, we are infact targetting some performance enhancements in #27735 and #27734.

Meanwhile, I would recommend that you try with less products per page, perhaps 75 or even 50 to see if that helps. I am closing this issue since we will be targetting performance bottlenecks in seperate granular issues, instead of a generic issue like this one.
