Error when trying to update a simple tile

[znb]

I'm trying to push data to a simple "text" tile using the curl command.

This is erroring out with

AttributeError: 'NoneType' object has no attribute 'write_message'
[E 181022 16:21:44 iostream:319] Uncaught exception, closing connection.

If you need any more information, please let me know.
