CLI tricks?

I'm not having much luck with the CLI over BLE

Connecting to 'c8:71:9f:36:a5:ee'
Connected
****************************************­****************************
* No list of built-in modules found. If you get 'Module not found' *
* messages for built-in modules you may want to connect to a board *
* with '-p devicePath' or use '--board BOARDNAME'                  *
****************************************­****************************
Module neopixel not found

I'm setting puckjs in the jobfile

I've actually noticed this not found warning in the web ide - but scripts seem to work, so I've not paid much attention

The file seems to write - but leaves the device in a semi-broken state.

The file doesn't actually run - and subsequent attempts to connect via the web ide connect ok, but the repl is broken, sometimes I get this in the repl:

>Uncaught Error: String too big to convert to float
 at line 1 col 547
....stringify(process.env),">>",">")

I'm thinking of hooking an FTDI USB-serial adapter to see how much of this is specific to BLE
