Problem generating json

[MatejJan]

I also started to receive this error, similar to #246 and #243 from last year.

There is a problem to generate the json. If you save the current json, those values might modified:
_schema

Please open an issue at https://github.com/jeromelebel/mongohub-mac/issues

In my case, the _schema field is a string and if I look at the generated json it all still looks OK. Excerpt:

  },
  "_schema": "2.0.0"
}

Many other documents from same collection open without error, but I'm trying to debug an issue where my server started running out of memory very rapidly, so I'm trying to assess if this could have lead to a corrupt DB state somehow, triggering some of my other app code to go into infinite loops or memory leaks.
