Attempt to catch error and log. Any other method of logging would be preferred.

closes #1086

As far as I understand, if we are trying to handle the circular dependency scenario, can we reproduce with a test?

I think it should be enough to have this in a form like

const result = {test:true};
result.circular = result;
...
res.status(200).json(result);

@kmcrawford I made a PR to this branch to integrate the tests. Have a look 👍
