A Node.js client was putting load on a key and the server was showing the following in the log:

The server now knows the data types, so it could figure out that this key of "text/plain" and could use the info to present the key in its text format as opposed to binary. This would help with diagnose/debugging.
By trying out different keys I figured the key here was "leaderboard"
