Is Strawberry UploadFile has a limit size ?

[DayaJuang]

I am working using strawberry-graphql and fastAPI UploadFile to upload a file (image). Whenever I uploaded a file that less than 1MB, it worked fine but when I am uploading a file larger than 1MB it throw an error like this

strawberry.execution - cannot pickle '_io.BufferedRandom' object

I don't know if this error is from the strawberry or from fastAPI

@DayaJuang I don't think we do anything particular with the file, so it might be FastAPI 😊

I found the problem was cause by converting to pydantic model using input.to_pydantic() where my image file was in the input.
It worked fine when i only upload the file that less than 1MB. So, pydantic is not a good practice to do a file/image validation ?
