Bug fix for turning empty objects into struct

[k1o0]

Mind testing to see if this also resolves the issue with saving the hardware JSON on the zrigs?

what was the issue with saving JSON on the zrigs?

You mentioned that the hardware JSON wasn't saving on ZRIG4. When a new experiment is started expServer takes the current rig object (loaded from hw.devices) and saves it as a JSON file. This includes the current Git commit that the code is running.

https://github.com/cortex-lab/Rigbox/blob/master/%2Bsrv/expServer.m#L276-L286

    % save a copy of the hardware in JSON
    fid = fopen(dat.expFilePath(expRef, 'hw-info', 'master', 'json'), 'w');
    fprintf(fid, '%s', obj2json(rig));
    fclose(fid);
    if ~strcmp(dat.parseExpRef(expRef), 'default')
      try
        Alyx.registerFile(hwInfo);
      catch ex
        warning(ex.identifier, 'Failed to register hardware info: %s', ex.message);
      end
    end

I don't know what the problem is on ZRIG4 but I recently discovered an error in my obj2struct code that occurs when you try to turn an empty instance of an object into a struct. That's what this fix is for.

ah right, will check now

the issue here is simply that the variable 'hwInfo' is undefined

That's terrible! How long have the rigs been failing to register the hardware??

The answer is Dec 19th. I'm going to have to push a hotfix for this...
