UnhandledPromiseRejectionWarning Error

Hello All,

I’m using Node 14 and seem to be running into this error when adding simple test data to solr:

const solr = require('solr-client');
const client = solr.createClient();

client.add({ id: 12, title_t: 'Hello' }, function(err, obj) {
       if (err) {
            console.log(err);
        } else {
            console.log('Solr response:', obj);
        }
}

(node:39116) UnhandledPromiseRejectionWarning: Error: Request HTTP error 404: at Client.doRequest (…/node_modules/solr-client/dist/lib/solr.js:141:19) at processTicksAndRejections (internal/process/task_queues.js:95:5) (Use node --trace-warnings ... to show where the warning was created) (node:39116) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag --unhandled-rejections=strict (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1) (node:39116) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Appreciate any help. Thank you

@ranrao Do you use Docker? This is how we init Solr Docker image:

services:
  solr:
    container_name: solr_dev
    image: solr:8.9.0
    ports:
      - "8983:8983"
    networks:
      - proxynet
    volumes:
      - data:/root/solr
      - /root/solr:/opt/solr-8.9.0/customSettings
    entrypoint:
      - bash
      - "-c"
      - "precreate-core testcore; precreate-core vehicles; precreate-core users /opt/solr-8.9.0/customSettings/users; precreate-core organizations; precreate-core classifiers; precreate-core departments; precreate-core roles; exec solr -f"
    hostname: solr_hostname

Thank you @kibertoad. Tried creating a Solr core and it is all working very well now. Such timely help. Really appreciate it.
