cannot pass value to parameter typed as ID

Is it anyhow possible to pass a value to an ID typed parameter like below ?

I am trying to get repository information from GitHub. Therefore I created a parameterized query that expects $id of type ID!

Whenever I try to pass an ID Value like “MDEwOlJlcG9zaXRvcnk1NDc4MjE2MQ==” I get this:

Error: GraphQL error: Variable id of type ID! was provided invalid value

When I switch the parameter type from ID to String I get:

Error: GraphQL error: Type mismatch on variable $id and argument id (String / ID!)

Here’s the query definition:

private repositoryByIdQuery: any = gql`
      query repositoryById($id: ID!){
        node(id: $id){
           ...repositoryFragment
        }
      }
      
      fragment repositoryFragment on Repository {
        id
        description
        isPrivate
        name
      }
    `

Here’s the executing code:

public getById(id: string): Promise<any> {

  return new Promise<any>(
    (resolve, reject) => {
      this.githubClient.query({
            query: this.repositoryByIdQuery,
            variables:{
              id: id
            }
        }).then(
        ({loading, data}) => {
        if(!loading){
          console.log(data); 
          resolve(data);
        }
      },(reason) => {
        console.log("hello from rejected"+  reason);               
        reject(reason);
      });
    }
  )
}

If your schema looks something like this:

    type Repo {
        id: ID!
        .......
        .......
    }
    type Query {
        getRepo(id: ID!) : Repo
    }

You can execute your query like this:

    query getRepo($id: ID!) {
        getRepo(id: $id) {
              id
              .......
              .......
        }
    }

Make sure you use exact same type in query that you used while defining your schema, otherwise the GraphQL parser will yell at you.

Let me know if this helps. 😃

Just answered it myself - I was querying with query repositoryById($id: String!){ instead of query repositoryById($id: ID!){
