If you check the `/docs`, they will show that the field `data` expects base64 encoded bytes:

If you need GraphQL, I still would recommend you check out [Strawberry](https://strawberry.rocks/), as it's based on type annotations instead of custom classes and types.

    * The generated schema will specify that it's a `str` with `binary` "format".
* `Decimal`:
    * Standard Python `Decimal`.
    * In requests and responses, handled the same as a `float`.
* You can check all the valid Pydantic data types here: [Pydantic data types](https://docs.pydantic.dev/latest/usage/types/types/).

## Example { #example }

Here's an example *path operation* with parameters using some of the above types.
