Can't get past pageNum=1001

I’m trying to do a search using OneMap’s REST API.

There are totalNumPages of 14181 with regards to my SearchVal, but I can’t seem to get past pageNum = 1001. I am able to access pageNums from 1 through 1000.

Anyone encountered the same error?

Best regards,
Zhe Kai

Please narrow down your SearchVal as you have too many matches found.
