Trying to delete api key but getting "await is only valid in async function"

Question

I'm trying to delete api keys using AWS SDK JS, but I'm receiving this error message:

{
    "errorType": "Runtime.UserCodeSyntaxError",
    "errorMessage": "SyntaxError: await is only valid in async function",
    "stack": [
        "Runtime.UserCodeSyntaxError: SyntaxError: await is only valid in async function",
        "    at _loadUserApp (/var/runtime/UserFunction.js:98:13)",
        "    at Object.module.exports.load (/var/runtime/UserFunction.js:140:17)",
        "    at Object.<anonymous> (/var/runtime/index.js:36:30)",
        "    at Module._compile (internal/modules/cjs/loader.js:701:30)",
        "    at Object.Module._extensions..js (internal/modules/cjs/loader.js:712:10)",
        "    at Module.load (internal/modules/cjs/loader.js:600:32)",
        "    at tryModuleLoad (internal/modules/cjs/loader.js:539:12)",
        "    at Function.Module._load (internal/modules/cjs/loader.js:531:3)",
        "    at Function.Module.runMain (internal/modules/cjs/loader.js:754:12)",
        "    at startup (internal/bootstrap/node.js:283:19)"
    ]
}

I've tried to create a promise to delete, just like I did to select keys, but I think it might be a problem to do it inside a foreach.

My code:

let sendPromise = null;
let params = {
    includeValues: true,
    limit: 500
};
let dados = null;

sendPromise = new AWS.APIGateway().getApiKeys( params ).promise();

try {
    dados = await sendPromise;
} catch(err) {
    console.error(err, err.stack);
    return criarResposta( 500, `{
        "message": "Erro interno"
    }` );
}

dados.items.forEach( chave => {
    const paramsDeletar = {
        apiKey: chave.id
    };

    sendPromise = new AWS.APIGateway().deleteApiKey( params ).promise();

    try {
        let dadosDeletar = await sendPromise;
    } catch(err) {
        console.error( err, err.stack );
        return criarResposta( 500, `{
            "message": "Erro interno"
        }` );
    }
});

return criarResposta( 200, JSON.stringify( dados ) );

Other thing, do I need to wait for all my promises individually or there is a way of wait for promise's bundle? I can't not wait for my promise, because I'm using lambda, but I wish I could let them running together

Here you better replace the forEach loop with a for loop, that way will be able to use the await in it:

...
for (const chave of dados.items) {
    const paramsDeletar = {
        apiKey: chave.id
    };

    sendPromise = new AWS.APIGateway().deleteApiKey( params ).promise();

    try {
        let dadosDeletar = await sendPromise;
    } catch(err) {
        console.error( err, err.stack );
        return criarResposta( 500, `{"message": "Erro interno"}` );
    }
}
