Invalid Identifier

This error occurs when you use an invalid identifier in your HelixQL query.

Erroneous Code Example

This error occurs when you use an invalid identifier in your HelixQL query. For example, Out is a reserved keyword so it cannot be used as a variable or a parameter name.

QUERY getUser(id: ID) =>
    Out <- N<User>(id)
    RETURN Out

QUERY getUser(Out: ID) =>
    user <- N<User>(Out)
    RETURN user

Solution

Rename the variable or parameter to a valid identifier.

QUERY getUser(id: ID) =>
    user <- N<User>(id)
    RETURN user

QUERY getUser(id: ID) =>
    user <- N<User>(id)
    RETURN user
