Hello,

I am receiving this error when I run a batch job on my accounts: The flow tried to update these records: null. This error occurred: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY: DrivingDistanceTrigger: execution of AfterUpdate caused by: System.AsyncException: Future method cannot be called from a future or batch method: DrivingDistance1.calculateDistances(String) ()

I need this flow to work, but I don't know what is going wrong.  Please help!

Class:

public class DrivingDistance1 {
    
    public static boolean isExecuting = false;
    
    public static void execute(List<Account> triggerNew, list<Account> triggerOld){
        //filter unneeded objects
        //modify needed objects
        //save!
       	list<Account> filtered = filterAccounts(triggerNew, triggerOld);
        if(!System.isFuture()){
            for(Account f:filtered){
            	calculateDistances(f.id);
       		}
        }
    }

        List<Account> returnList = new List<Account>();
        for(Integer i = 0; i < triggerNew.size(); i++){
            if((triggerOld[i].UCO_service_provider__c != triggerNew[i].UCO_service_provider__c) || (triggerOld[i].shippingStreet != triggerNew[i].shippingStreet) ){
                returnList.add(triggerNew[i]);

Trigger:

trigger DrivingDistanceTrigger on Account (after update) {
    
    // because were running in an after update context
    // we have trigger.new, and trigger.old 
    //engage semaphor when the uco object or address has changed
    // disengage when it's not
	DrivingDistance1.execute(Trigger.New, Trigger.Old);
