almond-scalafmt doesn't work: "WARN Kernel Ignoring unhandled message"

[suevii]

Hi,

I installed the almond-scalafmt but it doesn't work(the cell is not formatted successfully), and the jupyterlab log shows:

WARN Kernel Ignoring unhandled message:
Message(Vector(ArraySeq(101, 50, 48, 100, 101, 98, 98, 101, 45, 48, 51, 99, 50, 45, 52, 97, 98, 57, 45, 57, 101, 100, 51, 45, 57, 99, 51, 101, 57, 102, 98, 100, 52, 53, 55, 101)), {"date":"2022-01-10T02:46:00.177Z","msg_id":"d008c7e2-5fa0-4cc6-9192-489c3dfa9859","msg_type":"format_response","session":"e20debbe-03c2-4ab9-9ed3-9c3e9fbd457e","username":"","version":"5.2"}, {}, {}, {"cells":{"0ee776a6-5801-4fad-8a6c-f263b74836c1":"println ("Hello World!")"},"conf":{}})

It seems the response is not received or what.

Version info:

@almond-sh/scalafmt: 0.1.1
almond: 0.11.2
jupyterlab: 3.1.18

By the way, could you tell me how to check the almond version? I know its version only because I specified the version when I install almond:
cs launch --fork almond:0.11.2 --scala 2.12.11 -M almond.ScalaKernel -- --install

Hi almond-scalafmt has not been updated for jupyterlab 3 yet.
You can get almond version with almond.api.Properties.version.

Thank you for the reminder, but unfortunately I tried it on jupyterlab 2.3.2 and it still report the same warning and still doesn't work.
