models.Base.metadata.create_all(bind=engine)

SECRET_KEY = '[SECRET KEY]'
ALGORITHM = 'HS256'

    return {'token', token}

@app.post('/login/{method}')
async def login(method: str, form_data: OAuth2PasswordRequestForm = Depends(), db: Session = Depends(get_db), ):
    user = services.authenticate_user(form_data.username, form_data.password)
    if not user:
        raise HTTPException(
            status_code=status.HTTP_401_UNAUTHORIZED,
            detail="Incorrect username or password",
            headers={"WWW-Authenticate": "Bearer"},
        )
    access_token_expires = timedelta(minutes=ACCESS_TOKEN_EXPIRE_MINUTES)
    access_token = services.create_access_token(
        data={"username": user.username, "email": user.email}, expires_delta=access_token_expires
    )
    return {"access_token": access_token, "token_type": "bearer"}

Description

I saw the solution is changing ‘main’ -> ‘src.main’ so I tried that, but the same problem is occuring Even if I use ‘cd src’ to move to src and run ‘uvicorn main:app --reload’, errors continue. What do I need?
