Has anyone come across this error when trying to use Process Builder/@InvocableMethod to call an Apex class?

This is the error I see in the Debug log:

Could not evaluate formula for value passed to Flow Generate_Royalty_Invoice. FlowDefId: 300w0000000CnEL FlowVersionId: 301w00000000IGr: Index: 1, Size: 1

This is the error I receive in data loader:

Error message:The record couldn't be saved because it failed to trigger a flow.

This only occurs when:

  • Data is loaded via data loader
  • There is more than one record loaded

i.e., it does not happen for records inserted manually or via Apex.

There are no errors in the @InvocableMethod



Here's as much of the InvocableMethod that you need to see, it successfully processes one ItemToProcess and then fails seemingly after that - it would eventually go on to pass the id's gathered to a batch job, but it never gets that far (unless you're only processing one record). If I run each record separately, it works every time:

global class RoyaltyProcessingService 
    @InvocableMethod(label='Process Royalty' description='Processes Royalty Invoice')
    global static void process(List<RoyaltyProcessingService.ItemToProcess> itemsToProcess) 
        Set<Id> invoiceTypeIdsToProcess = new Set<Id>();
        Map<Id,Set<Id>> accountIdsToProcess = new Map<Id,Set<Id>>();

        for(RoyaltyProcessingService.ItemToProcess itemToProcess : itemsToProcess)
            process(itemToProcess.Input, invoiceTypeIdsToProcess, accountIdsToProcess, itemToProcess.InvoicesArePosted);

The Process itself is really simple, showing the action for convenience:

In essence, I am only using the Process as a form of Trigger, so I can switch on/off easily and also pass in a config Boolean - its so much more convenient than a Trigger, so it would be great to get it working.

  • Picklist values are not evaluated correctly in formulas when sObjects are passed in through flow triggers .Are you evalulating picklist in formula ?

  • No, there a no picklists on the object... Apr 29, 2015 at 18:27
  • There are a few bulkificaiton gothca's around with Process Builder, sadly more than i feel there should have been for v1 GA release. Can you share a screenshot of your setup and some sample code? May 3, 2015 at 13:06

I came across same error. But I set the return type to the same type of input parameter, it worked. I thought the return type of the InvocableMethod must not be "void" when it processes some records. Please try it!
