Initialisation error: "Can not call init more than once" [FastAPI]

[SahandJ]

I've installed and imported json_logging. I then initialised the module like this:

import json_logging

from app.routers.jobs import jobs

load_dotenv()

app = FastAPI()
app.include_router(jobs.router, tags=["jobs"])

json_logging.init_fastapi(enable_json=True)

but this returns the following error:

RuntimeError: Can not call init more than once

I'm not sure why it's being initialised more than once. Any advice?
