Update an existing custom dimension, or insert if not present

I have a script to insert Google Analytics custom dimensions. This is useful for new GA properties i want to copy custom dimensions over to. It will append if there are existing custom dimensions in the destination properties.

Therefore, i want to use

Analytics.Management.CustomDimensions.update() 

function updateCustomDims() {
  var sourceProperty = 'UA-XXXXXXXX-1' 
  var sourceAccount = 'XXXXXXXX'
  var sourceDimensions =             Analytics.Management.CustomDimensions.list(sourceAccount, sourceProperty)
  var sourceItems = sourceDimensions['items']
  var destinationProperty = 'UA-XXXXXXXX-1'
  var destinationAccount = 'XXXXXXXX' 
  var destinationDimensions =     Analytics.Management.CustomDimensions.list(destinationAccount, destinationProperty)  
  var destinationItems = destinationDimensions['items']
  for (var i = 0; i < sourceItems.length; i++) {
    var sourceContent = {
      'name': sourceItems[i]['name'],
      'scope': sourceItems[i]['scope'],
      'active': sourceItems[i]['active']
    }

    for (var i = 0; i < destinationItems.length; i++) {
      var destinationContent = {
        'name': destinationItems[i]['name'],
        'scope': destinationItems[i]['scope'],
        'active': destinationItems[i]['active']
      }
      var cdId = {'id': destinationItems[i]['id']}     

      if (destinationContent[i] != undefined) {
        Analytics.Management.CustomDimensions.update(sourceContent, destinationAccount, destinationProperty, cdId)
      } else {
        Analytics.Management.CustomDimensions.insert(sourceContent, destinationAccount, destinationProperty)
      }
      Utilities.sleep(1000) 
    }
  }
}

It will only append even though there are existing custom dimensions. It should update the existing dimension.

Probably your issue is that you are accessing an object with an integer key and not the name of the key: destinationContent[i] becomes destinationContent[0], destinationContent[1], etc. Yet you clearly have defined destinationContent to have only the keys name, scope, and active. You also have a double-use of the iterator variable i, which is certainly going to make your script behave in exceedingly confusing manners.

Note that a proper API reference link is this one with the underlying REST API resource here.

Assuming you want to check if a particular source dimension already exists in the destination, and if so, update it (vs. inserting it), you would want to do something like:

// Create an associative map between the name of a custom dimension
// and its ID (rather than search an array repeatedly).
const existingDims = destinationItems.reduce(function (acc, item) {
  var name = item.name;
  acc[name] = item.id;
  return acc;
}, {});

sourceItems.forEach(function (sourceItem) {
  // Construct the resource for this source item.
  var name = sourceItem.name;
  var sourceContent = {
    name: name,
    scope: sourceItem['scope'],
    active: sourceItem['active']
  };

  // Does this resource exist already?
  var existingId = existingDims[name];
  if (existingId)
    // update
  else
    // insert
});
