lnet broke with newer c-lightning API?

[renepickhardt]

I wanted to run lnet today on lightning 0.7.3.10 and I realized that lnet gives me the following output after spinning up the network:

./lnet-cli node server getinfo 
{"error": {"code": 500, "data": null, "message": "OtherError: _writeobj() missing 1 required positional argument: 'obj'", "name": "OtherError"}, "id": "5f214e7b-d9e4-4133-b972-6c6213f00fde", "jsonrpc": "2.0"}

also the process of spinning up the nodes did not fully execute. However htop tells me that the lightning nodes are running. before I start chasing down and debugging the error is there any quick help?
