Troubleshoot Flow Error
My flow used to work perfectly fine, but now it does not; it converts a Quote to an Order. There is one input variable, which takes the ID for the quote you wish to convert. When performing a fast lookup the inputted variable reports as null, causing the rest of the flow to fail and error out. This doesn't make any sense. I have even validated that the input variable is being set correctly by displaying its value in a screen step right before performing the lookup, and it looks fine.
Has anyone else encountered this issue?
I might have miscommunicated my issue.
When you do the fast lookup, are you querying for the Quote based on the Quote Id, similar to this screen shot?
Last, did you add the pertinent fields to the Fast Lookup? Otherwise, nothing will come back.
I did make sure it was set to Input and Output, and my fast lookup looks almost exactly like yours. The flow error looks like this:
FAST LOOKUP: Get_Quote_Fields
Find all Quote records where:
Id Equals {!SourceQuoteID} (null)
Assign those records to {!oQuote}.
Save these field values in the variable: Id, ShipTo__c, SoldTo__c, Pricebook2Id, AccountId
Result
Failed to find records.
As you can see, the step reads the variable as null rather than having a value.
Normally, those errors are caused by either a bad query or the launching user doesn't have access to the record, but if you're calling from a button on the record that's not the case.
when did it stop working? Did anything change in the flow between it working and not working? Can you try a different version of your flow and see if that makes a difference?
This flow is normally accessed through a custom button, but for troubleshooting I have begun navigating to the URL directly and hard coding a specific Quote ID to be sure that there is no problems with the expansion of an object field value. ex (instance.salesforce.com/flow/quote_to_order?SourceQuoteID=quoteid)
There have been no changes to this flow in the last few months. It was working before TrailHead; now it is not.
Is this a production Org? Are you using this org to complete trailhead challenges?
I was under the impression there was a recent update to the backend of Salesforce; and that was called TrailHead. Am I mistaken?
Yes, this is a production organization.
This would not have impacted your flow whatsoever. There was a new release that came out for Salesforce, Winter '16. This was released between the end of September and the End of October depending upon your instance. You can find release dates at trust.salesforce.com. There wasn't anything in that update that should make this Flow fail on your fast lookup.
Let's try something a bit crazy. Save your flow as a new flow (not a version). Confirm your fast lookup and variables. Make sure the variable is set to input/output and note the capitalization of the variable. Make sure you don't have two variables with similar names - even if you aren't referencing one. I would also make sure you have a fault path for your fast lookup. that way when it does fault you can go to a screen with information on the variables and error message and not just get that "unhandled flow exception" message.
Next, test it. If it works, we'll chalk this up to Gremlins in your system. If it fails, and my guess is it will, then we have to look at what else changed in your org. It could be a permission issue on the record or object. It could a permission issue on the fields being referenced.
If all else fails, I think your next step is to grab screenshots of your whole flow and each element configuration and post them (individually or a link to the screenshots). Flow is notoriously difficult to debug right now and it could be that the error you're receiving isn't actually what the error is.
