I'm getting an object in str so JSON.parse will always failed

[adrienbarreau]

Json: (str) => {
      if(typeof str === 'string') {
          try {
              JSON.parse(str);
          } catch (e) {
              return false;
          }
          return true;
      }
      return true;
    },

Hi @adrienbarreau

I don't understand why you get an object in str, you should get a string on Json format.

If you have an object, the test should fail...
Did I miss something?

@GaelGRIFFON Your code is assuming that the input to the Json function will be a string, but actually, it's an object. That's because the exporter already exports it as a javascript object.
The exporter serializes everything as a json file and Json fields "could" be serialized as a string in Json format, but they're not. They're serialized as a plain old javascript object. Or null. Or undefined. Or 0. Or literally any serializable js type. We already know that it's valid json because the original 000001.json file was successfully parsed. So at the time the import validator is running, this could be any type and it would be "valid json". Give that, here's my proposed solution:

Json: () => true,

OK got it!
Thx you

@marktani @timsuchanek Can one of you please merge this? It's breaking a critical production feature for lots of people.

@dpetrick Since this is a critical bug, I agree this should be merged even if the graphcool-framework isn't a priority project for prisma.
