Hello, 

I'm receiving an error message System.DmlException: Insert failed. First exception on row 0; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, FeedItem: execution of AfterInsert caused by: System.QueryException: List has no rows for assignment to SObject. Class.InternalRequest_CreateNew.createNewIR: line 11, column 1
Trigger.FeedItem: line 13, column 1: []. This error occurs when I run my test class. 

I'm unsure why I'm getting this error since Class.InternalRequest_CreateNew.createNewIR: line 11, column 1 line is querying an Id that exist in the sandbox which is this line of code 

Id  cgroupId = [SELECT Id, Name FROM CollaborationGroup WHERE Name =: 'IRTicket'].Id;

 

Here's the trigger class. 

public class InternalRequest_CreateNew {

	public static void createNewIR(List<FeedItem> chatterpost){

		List<FeedItem> lGroupFeed = new List<FeedItem>(); 
		Map<Id,Id> mpostUserId = new Map<Id,Id>();
		Set<Id> sUserId = new Set<Id>(); 
		List<Ops_Priority_List__c> newIRtoInsert = new List<Ops_Priority_List__c>(); 
		Id internalRequestQuestionRecordTypeId = Schema.SObjectType.Ops_Priority_List__c.getRecordTypeInfosByName().get('Question').getRecordTypeId(); 

		Id  cgroupId = [SELECT Id, Name FROM CollaborationGroup WHERE Name =: 'IRTicket'].Id; 

		System.debug('cgroupId =' + cgroupId); 

        List<User> lUser = [SELECT Id FROM User WHERE ProfileId = '00ea00000021duy']; 
        Set<Id> userIds = new Set<Id>(new Map<Id, User>(lUser).keyset()); 
 	 
		for(FeedItem c : chatterpost){
			if((c.ParentId == cgroupId && userIds.contains(c.CreatedById)) || (c.Body.contains('@IRTicket') && userIds.contains(c.CreatedById))){
				lGroupFeed.add(c); 
				sUserId.add(c.CreatedById); 
				mpostUserId.put(c.Id,c.CreatedById);
			}
			System.debug('lGroupFeed =' + lGroupFeed); 
			System.debug('mpostUserId =' + mpostUserId); 
			System.debug('InsertedbyId =' + c.CreatedById); 
		}

		if(lGroupFeed.size()>0){
			System.debug('lGroupFeed size = ' + lGroupFeed.size()); 

			for(FeedItem cg : lGroupFeed){
				
					Ops_Priority_List__c i = new Ops_Priority_List__c(
						OwnerId = mpostUserId.get(cg.Id),  
						Description__c = cg.Body.stripHtmlTags() + '   ' + URL.getSalesforceBaseURL().toExternalForm() + '/_ui/core/chatter/groups/GroupProfilePage?g=' + cgroupId + '&fld=' +cg.Id,   
					 	Name = 'Questions from Chatter',   
						Status__c = 'New', 
						RecordTypeId = internalRequestQuestionRecordTypeId); 
						newIRtoInsert.add(i); 
			}
			System.debug('newIRtoInsert = ' + newIRtoInsert); 
		}
		if(!newIRtoInsert.isEmpty()){
			try{
				database.insert(newIRtoInsert,false); 
			} catch(DMLException e){
				System.debug('The following exception has occured: '+ e.getMessage()); 
			}
