Malformed JSON return from Gaoa RPC GET /txs Search transactions

Hi, I am using Gaia-Lite GET /txs to search transactions by events. I notice that whenever I set the search limit over 10 with pagination, I always run into malformed JSON returns from the server. When the limit is equal or under 10, things seem to be ok.

Has anyone encountered similar issues, or, am I missing something basic here? Thanks!

Here is an example of my query, which you could also try out (the return message breaks very consistently).
