### What happened?

I received the following cryptic error

```
/[path]/node_modules/@octokit/graphql/dist-node/index.js:81
throw new GraphqlResponseError(requestOptions, headers, response.data);
^

GraphqlResponseError: Request failed due to following response errors:
- Variable $number of type Int! was provided invalid value

What I expected instead is that the `new Project()` constructor should throw immediately when an invalid number was passed
