I just re-created the sender.js and it goes well. I think he wrote something wrong. The important thing is that I could check how the data exchange between lambda and SQS works. Thank you!
Only a tiny addition:
if (err) {
console.log('error:', "failed to send message" + err);
responseCode = 500;
responseBody = err;
...
I did not understand the concurrency part yet. If my Lambda has more than 2000 records to send to SQS, I will send them one by one to the queue. I think the lambda will take a long time, can I send batch queues? Each record is a message to the queue.
Maybe it illuminates us with an additional post about this?

Thank you so much Marcin!
you are allowed to send at most 10 messages in single batch docs.aws.amazon.com/AWSSimpleQueue...
I would delegate this task to multiple lambdas if you need to send batches concurrently to speedup.
