AWS SDK (v3) Typescript - send() request crashing the app with no error

[petr-hybler]

I have this application where I am registering Route53 records or removing them eventually...

I also have this function to check if the record exists:

private async doesRecordExist(recordName: string): Promise<boolean> {
   let isTruncated = true;
   let nextRecordName: string | undefined;
   let nextRecordType: RRType | undefined;

   try {
     while (isTruncated) {
       const existingRecordsCommand = new ListResourceRecordSetsCommand({
         HostedZoneId: this.HOSTED_ZONE_ID,
         StartRecordName: nextRecordName,
         StartRecordType: nextRecordType
       });

       let existingRecords = null;

       try {
         existingRecords = await this.route53.send(existingRecordsCommand);
       } catch (error) {
         Logger.error({ action: 'awsManager', _step: 'doesRecordExist::sendExistingRecordsCommand', _details: error });
       }
       if (existingRecords.ResourceRecordSets.some(record => record.Name === recordName && record.Type === 'A')) {
         return true;
       }

       isTruncated = existingRecords.IsTruncated;
       nextRecordName = existingRecords.NextRecordName;
       nextRecordType = existingRecords.nextRecordType;
     }

     return false;
   } catch (error) {
     Logger.error({ action: 'awsManager', _step: 'doesRecordExist', _details: error });
   }
 }

When I print the content of existingRecordsCommand it says:

{
    "middlewareStack": {},
    "input": {
        "HostedZoneId": "<replaced_my_zone_id>"
    }
}

It gets only to the point where I am sending the request await this.route53.send(existingRecordsCommand); and then my nodejs app crashes... Any idea why is it crashing the app with no error provided?

To make it a bit more interesting.. for the first call, it works fine .. but second call crashes the app :(

Btw I am using "@aws-sdk/client-route-53": "^3.515.0",

$ curl --location --request POST 'http://localhost:8080/api/v1/domain/remove' --header 'Content-Type: application/json' --data-raw '{ "subdomain": "test" }' curl: (52) Empty reply from server
