I have figured out how to make the changes to get it to output the correct data in the correct format, but now I am getting a "Premature end of script headers" error. I have the correct #! line and the output from the command line shows no errors that would be interfering. Is there a way to make sure it is showing me all the errors? To increase error logging?

You top-posted, so I have to clip both the earlier messages out.  On
this forum, we put responses immediately AFTER the part we quoted.

I don't see how I can possibly help further, without buying a hubot of
my own.  I don't know what operating system you're running this on, nor
what the command lines look like.  I have no idea how the stdout of your
script migrates over to the hubot's processor.  Nor why it only gets
some of the stdout.

You could give us more environmental data (OS version, command line, any
messages, ...), or tell what the hubot's docs say you should use as a

Perhaps you need a blank line to be output here.  One way is just print
by itself.

Where do you alert the user about this exception?

You should probably send this and any other error messages to stderr, as
stdout is presumably being consumed by the robot.
