TypeScript throws error for not being able to find a module

Question

I have a Node.js express application that is serving an Apollo GraphQL API serving as a BFF for a React Application.

The project uses the latest graphql npm package of 16.8.0 and it utilizes the graphql-contstraint-directive package.

Now when I build my project — build script is "build": "tsc" — it throws this error:

node_modules/graphql-constraint-directive/index.d.ts:3:32 - error TS2307: Cannot find module 'apollo-server-core' or its corresponding type declarations.

3 import {PluginDefinition} from "apollo-server-core";
                                 ~~~~~~~~~~~~~~~~~~~~


Found 1 error in node_modules/graphql-constraint-directive/index.d.ts:3

Looking at the latest package in Github here, it looks to be using the PluginDefinition from apollo-server-core which is deprecated. In addition, the package.json file does not seem to add the apollo-server-core as a dependency, which is strange. (refer here).

Has anybody run into this issue before ? If so, how did you solve it ? I guess I could try installing the deprecated apollo-server-package but that does not seem right.

Any help is appreciacted.
