Non existant data_path in OSC config may keep the server from launching

[joncraig]

I have worked around this by not having a bad config file but FYI...

I think I am running the v2.4.1 but it says v2.3.2 in the add-ons page. So its one of those two(?)

Seems like when I had a data_path that listed something that didn't exist it crashed the OSC sever as it tried to open. The UI didn't reflect that there had been a problem.
Although now that I read the console more closely perhaps I generated a bad character in there somehow?

Anyhow, if you care to you could guard the config read to update the UI with an error, or at least to not show osc py server running if the config fails to read in, or the server fails to start?

Thanks for making this. Love having another osc enabled tool

I had a typo in my osc config file where the data_path was

        ...
        "data_path": "bpy.data.objects[\"Plat32\"].dimensions",
        ...

Rather than "Plate3"

 {
        "address": "/Projection/Plate/3/d",
        "data_path": "bpy.data.objects[\"Plate3\"].dimensions",
        "osc_type": "f",
        "osc_index": "()",
        "osc_direction": "OUTPUT",
        "filter_repetition": false,
        "dp_format_enable": false,
        "dp_format": "args",
        "loop_enable": false,
        "loop_range": "0, length, 1",
        "enabled": true
    }

Looking at the console it seemed to keep the OSC server from launching:
