Can't merge schemas using mergeSchemas

[panjizhi]

when merge multiple schemas using mergeSchemas, it throw error

Error: Can't find type Root.

const { mergeSchemas } = require('graphql-tools')
const { getSchema } = require('graphql-sequelize-crud')

const dbschema1 = getSchema(sequelize1)
const dbschema2 = getSchema(sequelize2)

module.exports = mergeSchemas({
  schemas: [dbschema1, dbschema2]
})

Could you provide a small repository reproducing this?

i've same issue, graphql-tools from apollo server needs that schema must be defined with typeDefs for Schema Stiching:

@panjizhi i'm using a workaround, you've just to add this in your code:

const linkTypeDefs = `
  type Root {
    _: Boolean
  }
`;

module.exports = mergeSchemas({
  schemas: [dbschema1, dbschema2, linkTypeDefs]
})

Let me know
