The 502 status code returned by you will appear in 90% of the cases where we use the rest api for product update. This has been the case since April 2, 2022, and the rest api called is /admin/api/2020-10/products/{product_id}.json, the following two domain names have this situation shopnewbella.myshopify.com and moco-official.myshopify.com
Along with the 502 error code mentioned, there should also be an x-request-id response in the headers returned. Can you log this value for a request with the specific error and share it back here? An an example of the request payload body that was sent would also be helpful.
With that, I can take a closer look, provide insights, suggestions, or next steps moving forward - Cheers!
