Prisma

Hey guys, I trying the new version, I made the choice of the typescript-basic (incl. database), I tried the mutation signUp and login, it always return me "Unexpected token T in JSON at position 0"; Have you an idea about this ?

Got this : ```GraphQLError: Unexpected token T in JSON at position 0
    at Object.locatedError (.\node_modules\graphql\error\locatedError.js:23:10)
    at Object.checkResultAndHandleErrors (.\node_modules\graphql-tools\src\stitching\errors.ts:83:11)
    at Object.&lt;anonymous&gt; (.\node_modules\graphql-tools\src\stitching\delegateToSchema.ts:91:14)
    at step (.\node_modules\graphql-tools\dist\stitching\delegateToSchema.js:40:23)
    at Object.next (.\node_modules\graphql-tools\dist\stitching\delegateToSchema.js:21:53)
    at fulfilled (.\node_modules\graphql-tools\dist\stitching\delegateToSchema.js:12:58)
    at &lt;anonymous&gt;
    at process._tickDomainCallback (internal/process/next_tick.js:228:7) ```

Tested the same in **node-basic**, everything is working
