'Lambda timeout on sqs sendmessage

I'm sending messages to a queue from a lambda function. But some times sqs.sendMessage dont return anything and the lambda get timeout. This happens sometimes

I tried changing de code many times, to work with await, promises and callback but the error persist.

Lambda log

const sqs = new aws.SQS({apiVersion: '2012-11-05'});

//TODO: Validar campos obrigatórios nas mensagens de acordo com o tipo de mensagem
exports.sendMessage =  async (message) => {
  let params = {
    MessageBody: JSON.stringify(message),
    QueueUrl: 'https://sqs.us-east-1.amazonaws.com/....',
  };

  try {
    await sqs.sendMessage(params).promise();
    return {statusCode: 200, body: {data: "Notification sent successfully"}};
  } catch (e) {
    return {statusCode: 400, body: {data: e}};
  }
}

I had a similar issues. What I did to make it work was add in the endpoint url into the boto3 client call.

For Example: boto3.client('sqs',endpoint_url='https://YourVPCDNSEndpointforSQS')

I just had the same issue. The problem was that the lambda had 3 subnets assigned to it and only 1 of them had a routing entry to 0.0.0.0/0 Even tho 2/3 of the subnets were missing that routing entry, only 1-3% of the requests randomly timed out, so make sure to check that!
