Repro for SOFA issue #1174

This project reproduces SOFA issue #1174: After SOFA v0.12.0 upgrade, "Variable X of required type String! not provided" errors for multiple mutations.

In this repro project, Express serves: A GraphQL API (through an interactive iGraphQL UI) and a (SOFA) REST API (with interactive Swagger docs/UI), for accessing data stored in an SQLite DB, via the Prisma ORM. CRUD resolvers for db models are auto-generated by Type-Graphql to node_modules/@generated/type-graphql, while custom resolvers are defined in src/resolvers.ts. The resulting schema can be found in code in src/index.ts, and in text at src/generated/gql-schema.graphql.

Steps to reproduce:

1. Install required packages

npm install

2. Set up

npm run setup

This creates the Prisma (ORM) db client, generates the TypeGraphQl CRUD resolvers, and initializes the SQLite db.

3. Start the server

npm run dev

3. Request the endpoint: /rest/login-by-phone

From SwaggerUI (at the /rest-docs endpoint) test the endpoint: /rest/login-by-phone.

With SOFA v0.12.0 (see package.json), this request results in the error:

Variable "$phone" of required type "String!" was not provided.

From server output (see src/index.ts), however, it is clear that the phone string parameter has been received by the server:

request:
  url:
     /rest/login-by-phone
  body:
     { phone: 'string' }

When the SOFA version is rolled back to v0.11.2 (by editing package.json's "sofa" entry, removing package-lock.json, and re-doing steps 1-3 above) - the request above is handled perfectly.
