I am trying to make the file upload work and no luck yet I got back to the example on https://strawberry.rocks/docs/guides/file-upload#sending-file-upload-requests but just copy past multi file requests from postman returns "Unsupported content type"

    for file in files:
        content = file.read().decode("utf-8")
        contents.append(content)
    return contents

@itsklimov sorry about that! we recently release a change that disabled multipart uploads by default you can see it here: https://strawberry.rocks/docs/breaking-changes/0.243.0

you need to update your view config, here's how can do it with django: https://strawberry.rocks/docs/integrations/django#options (the param should be the same for all the integrations)

I'll keep this open so we can update that doc page :)

from fastapi import FastAPI, UploadFile, File
from strawberry.fastapi import GraphQLRouter

from src.config import settings
from src.schemas.graphql import schema
from src.utils.logger import logger

async def lifespan(app: FastAPI):
    logger.info("GraphQL File Server is starting...")
    yield
    logger.info("GraphQL File Server is shutting down...")

app = FastAPI(title="GraphQL File Server", lifespan=lifespan)

graphql_app = GraphQLRouter(schema)
app.include_router(graphql_app, prefix="/graphql")

if __name__ == "__main__":
    import uvicorn

    uvicorn.run(
        "app:app",
        host=settings.host,
        port=settings.port,
        reload=True,
    )

Can you advice on how to adjust app to enable it?

[patrick91]

This should be enough to make it work:

-graphql_app = GraphQLRouter(schema)
+graphql_app = GraphQLRouter(schema, multipart_uploads_enabled=True)

thanks resolved, do you want me to resolve the ticket or leave it opened

[patrick91]

let's leave it open, I think we should update the guide
