File adapter + Transformer works but emits unlabeled warning

[codepope]

Run any Transformer with the File adapter and the process will work but the console will be full of

unknown type: map[string]interface {}
unknown type: map[string]interface {}
unknown type: map[string]interface {}
unknown type: map[string]interface {}
...

Reason is the File adapter emits a map. The map is detected by the Transformer's transformOne function. This then calls mejson.Marshal(msg.Data). Mejson has no code to match with a map[string]interface() so it falls through to default...

default:
        fmt.Fprintf(os.Stderr, "unknown type: %T\n", v)
        return json.Marshal(v)
    }

which emits the error but still marshals the value allowing the code to work.

Don't know whether to fix in mejson or in the transformer.

Hi,
I think this was fixed with an update to mejson, ( compose/mejson@68a977b )
Can you please try go get -u github.com/compose/mejson and rebuild your transporter?

Thanks!

Fixed - wrong mejson was being pulled.
