Multiple Strawberry Fields Error

Description

This error is raised when using multiple strawberry.field() annotations inside an Annotated type. For example, the following code will raise this error:

from typing import Annotated

import strawberry


@strawberry.type
class Query:
    name: Annotated[
        str,
        strawberry.field(description="First"),
        strawberry.field(description="Second"),
    ]


schema = strawberry.Schema(query=Query)

This happens because Strawberry only allows one strawberry.field() per field when using the Annotated syntax. Having multiple would create ambiguity about which field configuration to use.

How to fix this error

You can fix this error by using only one strawberry.field() in your Annotated type annotation. Combine all the options you need into a single strawberry.field() call:

from typing import Annotated

import strawberry


@strawberry.type
class Query:
    name: Annotated[
        str,
        strawberry.field(
            description="The name",
            deprecation_reason="Use fullName instead",
        ),
    ]


schema = strawberry.Schema(query=Query)
