Projects API requst - https://developer.copper.com/projects/list-projects-search.html, has a limit of 100_000 records that it could return without any errors
Please note that search requests are limited to returning only the first 100,000 records regardless of the pagination parameters. If your search filter matches more than 100,000 records, we recommend modifying your search filter to separate your result set.
it’s not a reliable system, so I am wondering if there some limit of Projects objects count on Copper, e.g. if there is a limit of 20_000 Projects records then it’s ok to use request that returns a maximum of 100_000 records
