I have an eureka server with multiple clients, one of them is nodejs ,
all the java clients work as expected but the nodejs gives the following errors:

retrieved full registry successfully

registered with eureka:  dbServer/dbServer

eureka heartbeat FAILED, Re-registering app

retrieved full registry successfully

registered with eureka:  dbServer/dbServer

eureka heartbeat FAILED, Re-registering app

...

In the eureka server on the other hand I can see the following:

DS: Registry: lease doesn't exist, , registering resource: DBSERVER - dbServer 

Not Found (Renew): DBSERVER - dbServer

Registered instance DBSERVER/DBSERVER with status UP (replication=false)

Registered instance DBSERVER/DBSERVER with status UP (replication=true)

DS: Registry: lease doesn't exist, registering resource: DBSERVER - dbServer

Not Found (Renew): DBSERVER - dbServer

...

The client configuration(Node js):

const client = new Eureka({

// application instance information

instance: {

    app: 'dbServer',

    instanceId: 'dbServer',

    hostName: 'localhost',

    ipAddr: '127.0.0.1',

    port: {

        '$': port,

        '@enabled': 'true',

    },

    vipAddress: 'dbServer',

    dataCenterInfo: {

        '@class': 'com.netflix.appinfo.InstanceInfo$DefaultDataCenterInfo',

        name: 'MyOwn',

    },

    registerWithEureka: true,

    fetchRegistry: true

},

eureka: {

    // eureka server host / port

    host: 'localhost',

    port: 8761,

    servicePath: '/eureka/apps',

},

 });



   client.logger.level('debug');

   client.start((error) => {

           console.log(error || 'complete');

    });

Does anyone has a solution to this issue? it the commands still manage to arrive to the client but the logs are filled ,
Many thanks

PSo the answer is simple,

     instance: {

          app: 'dbServer',

          instanceId: 'dbServer',

InstanceId and app name cannot be identical.

Changeing any one will solve this issue.
