Solution

  • Topology was destroyed error comes, when mongodb was writing something and connection was closed/interrupted in middle.

    Have a look at the code which throws this error :

    Mongos.prototype.insert = function(ns, ops, options, callback) {
  if(typeof options == 'function') callback = options, options = {}, options = options || {};
  if(this.state == DESTROYED) return callback(new MongoError(f('topology was destroyed')));

  // Not connected but we have a disconnecthandler
  if(!this.isConnected() && this.s.disconnectHandler != null) {
    return this.s.disconnectHandler.add('insert', ns, ops, options, callback);
  }

  // No mongos proxy available
  if(!this.isConnected()) {
    return callback(new MongoError('no mongos proxy available'));
  }

  // Execute write operation
  executeWriteOperation(this, 'insert', ns, ops, options, callback);
}

    Solution :

    Kindly restart your mongodb and MongoDB compass as well, just to be on the safer side, and you should be able to create collections without any error.
