## Fixe a sua versão de `fastapi`

A primeira coisa que você deve fazer é "fixar" a versão do **FastAPI** que você está utilizando na mais atual, na qual você sabe que funciona corretamente para o seu aplicativo.

type Init struct {
	done uint32
	m    sync.Mutex
}

// Do is similar to sync.Once.Do - makes one successful
// call to the function. ie, it invokes the function
// if it is not successful yet.
func (l *Init) Do(f func() error) error {
	if atomic.LoadUint32(&l.done) == 0 {
		return l.do(f)
	}
	return nil
}

func (l *Init) do(f func() error) error {
	l.m.Lock()
	defer l.m.Unlock()

## Detalhes

O primeiro `"/static"` refere-se à subrota em que este "subaplicativo" será "montado". Portanto, qualquer caminho que comece com `"/static"` será tratado por ele.

O `directory="static"` refere-se ao nome do diretório que contém seus arquivos estáticos.

        fi

    # older suse linux distributions do not ship with systemd
    # but do not have an /etc/init.d/ directory

    # as well without failing this script

    // the fast path code. The safe min/max values are very unlikely to extend
    // into the range of surrogate characters, but if they do we must not test
    // any values in that range. To see why, consider the case where:
