💡 Hint

Common Mistakes

Using a nullable type when the argument is required.

Using the wrong type for an ID argument.

The 'ID!' type means the argument is required and must be an ID type, which is correct for identifying posts.

4fill in blank

hard

Fill both blanks to define a query with two arguments: 'limit' and 'offset'.

GraphQL

query getItems($limit: [1], $offset: [2]) { items(limit: $limit, offset: $offset) { id name } }

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Making both arguments required or both optional incorrectly.

Using wrong types like String or Boolean for numeric arguments.

'limit' is required so it uses 'Int!'. 'offset' is optional so it uses 'Int'.

5fill in blank

hard

Fill all three blanks to define a query with arguments 'search', 'limit', and 'offset' with correct types.

GraphQL

query searchItems($search: [1], $limit: [2], $offset: [3]) { items(search: $search, limit: $limit, offset: $offset) { id description } }

Drag options to blanks, or click blank then click option'

AString!

BInt!

DBoolean

💡 Hint

Common Mistakes

Forgetting to mark required arguments with '!'.

Using Boolean type for non-boolean arguments.

'search' is a required string, so 'String!'. 'limit' is a required integer, so 'Int!'. 'offset' is optional integer, so 'Int'.
