I got 100% code covergae. but i couldn't clear this challenge. the following is the error im getting when i check the challenge.
Challenge Not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Insert failed. First exception on row 0; first error: FIELD_INTEGRITY_EXCEPTION, Case: id value of incorrect type: 01t7F000003BjDmQAK: [Equipment__c].   

Can anyone please help me to fix this issue?

trigger Giveendclientname on Lead (before insert, before update) {
    List<ID> OppIds = New List<ID>();
    for(lead ld : Trigger.new){
        if(ld.Customer_Type__c == 'partner'){
            OppIds.add(ld.Customer_Type__c);
        }
        List<Opportunity> oppList = [SELECT id, EndClientName__c FROM Opportunity WHERE id in :OppIds];
    //    for(Lead opp : trigger.new){
            if(oppList.EndClientName__c == ''){
                //  oppList[i].status = 'Approved';
                oppList.addError('End client name should be given if it is a partner Account');
            }
           // oppList.add(opp);
            update oppList;
      //  }
    }
}

The requirement is, when the customer type in lead is partner, then the endclient name in opportunity should not be blank. it should throw an error.

When an opportunity goes into a certain stage, we would like tasks representing the “next steps” to be automatically generated. Requirements include:

1. Tasks should only be auto-generated for records with a record type of National Account
2. All tasks should be assigned to the opportunity owner
3. If the opportunity is moved to the next stage while there are incomplete auto-generated tasks, those open tasks associated with the prior stage should be closed, with a completed date reflecting the same date that the opportunity stage changed.
   1. Note that tasks that have been manually created by the user should be kept open.

The tasks to be auto-generated for each stage are as follows:

Stage	Tasks
Prospecting	Task Name: Complete Sales Information Due Date: 2 Business Days from Stage Start
Idea Generation	Task Name: Product Sourcing Due Date: 3 Business Days from Stage Start   Task Name: Send Presentation Due Date: 5 Business Daye from Stage Start   Task Name: Idea Presentation Follow Up Due Date: 8 Business Days from Stage Start
Sample Request	Task Name: Order Samples Due Date: 2 Business Days from Stage Start   Task Name: Sample Follow Up Due Date: 7 Business Days from Stage Start
Proposal / Price Quote	Send Quote – 5 Business Days from Stage Start Quote Follow Up – 7 Business Days from Stage Start
Negotiation / Review	N/A
Closed Won	N/A
Closed Lost	N/A
