error "invalid type: null, expected a string" when attempting to show cards on a board

New tro user here, trying to get tro to show the cards on a board. I run the following command:

tro -l DEBUG show "Dev"

And see a long debug output, that leads me to believe most of the conversation with the API goes OK, but it ends with this error

20:36:50 [DEBUG] (3) hyper::proto::h1::io: read 16384 bytes
20:36:50 [DEBUG] (3) hyper::proto::h1::io: read 16384 bytes

20:36:50 [DEBUG] (3) hyper::client::pool: pooling idle connection for ("https", api.trello.com)
An Error occurred:
error decoding response body: invalid type: null, expected a string at line 1 column 240450
20:36:50 [DEBUG] (1) tro: reqwest::Error { kind: Decode, source: Error("invalid type: null, expected a string", line: 1, column: 240450) }

I wonder if the Trello API has changed slightly and tro needs an update?

^^^ still an issue, I cannot use tro to access the board I need to access, because of this error
