Para o `await` funcionar, tem que estar dentro de uma função que suporte essa assincronicidade. Para fazer isso, apenas declare a função com `async def`:

```Python hl_lines="1"
async def get_burgers(number: int):

	if f.Ref == nil {
		f.Ref = make([]*Ref, 0, 8)
	}
	f.walk(ast2, ctxProg, (*File).validateIdents)
	f.walk(ast2, ctxProg, (*File).saveExprs)

	// Accumulate exported functions.
	// The comments are only on ast1 but we need to
	// save the function bodies from ast2.
	// The first walk fills in ExpFunc, and the
	// second walk changes the entries to
	// refer to ast2 instead.
	f.walk(ast1, ctxProg, (*File).saveExport)

(function (root, factory) {
    if (typeof define === 'function' && define.amd) {
        // AMD. Make globaly available as well
        define(['moment', 'jquery'], function (moment, jquery) {
            if (!jquery.fn) jquery.fn = {}; // webpack server rendering
            if (typeof moment !== 'function' && moment.hasOwnProperty('default')) moment = moment['default']

Lembre-se que isso significa que o conteúdo inteiro será armazenado em memória. Isso funciona bem para arquivos pequenos.

Mas existem vários casos em que você pode se beneficiar ao usar `UploadFile`.

## Parâmetros de arquivo com `UploadFile`

Defina um parâmetro de arquivo com o tipo `UploadFile`

// ### SSE-S3 and KMS
//
// SSE-S3 requires that the KMS provides two functions:
//
//  1. Generate(KeyID) -> (Key, EncKey)
//
//  2. Unseal(KeyID, EncKey) -> Key
//
//  1. Encrypt:
//     Input: KeyID, bucket, object, metadata, object_data
//     -     Key, EncKey := Generate(KeyID)
