Field type Json has no validator defined

[marktani]

Current behavior

Importing data to services with a Json field doesn't work. The error message

Field type Json has no validator defined

is returned.

Reproduction

Import data to a service that has a field of type Json or Json!.

Expected behavior?

It works.

Also hitting this issue, essentially making it so Graphcool has no working backup system since we can't restore a backup in production due to this import error

Same issue here...
I think you just have to add here:
https://github.com/graphcool/graphcool-framework/blob/0b80d3a8988fbaf6d9d4b2d55f2d586bc5e19e43/cli/packages/graphcool-cli-core/src/commands/import/Validator.ts#L41

Json: (str) => {
    try {
        JSON.parse(str);
    } catch (e) {
        return false;
    }
    return true;
}

or something like that... (can't test here...)

Edit: PR #513

Are there any workarounds?
Will it work if I downgrage graphcool?
Can't migrate my database to graphcool because of this :(
