In our project, we want to introduce an "alias" for a string, which is called CodeInput. Creating a custom scalar as described in the docs yields a pyright error.
Describe the Bug
Creating a custom scalar
CodeInput = strawberry.scalar(
NewType("CodeInput", str),
serialize=lambda v: v,
parse_value=lambda v: v,
)and checking it via pyright <file> yields:
