### Small Errors Automatically Handled { #small-errors-automatically-handled }

When building web APIs with FastAPI, if there's an error in our code, FastAPI will normally contain it to the single request that triggered the error. 🛡

{* ../../docs_src/dependencies/tutorial008c_an_py39.py hl[15:16] *}

Neste caso, o cliente irá ver uma resposta *HTTP 500 Internal Server Error* como deveria acontecer, já que não estamos levantando nenhuma `HTTPException` ou coisa parecida, mas o servidor **não terá nenhum log** ou qualquer outra indicação de qual foi o erro. 😱

### Sempre levante (`raise`) em Dependências com `yield` e `except` { #always-raise-in-dependencies-with-yield-and-except }

     * best we can do (since logging may overflow the stack) is to let the error propagate. Because
     * it is an Error, it won't be caught and logged by AbstractFuture.executeListener. Instead, it
     * can propagate through many layers of AbstractTransformFuture up to the root call to set().
     *
     * https://github.com/google/guava/issues/2254
     *
     * Other kinds of Errors are possible:
     *

     * Pre-processes API requests by checking access authorization before executing the action.
     * If access is not allowed, returns an unauthorized error response.
     *
     * @param runtime the action runtime context containing request information
     * @return ActionResponse with unauthorized error if access denied, otherwise delegates to parent
