An unhandled fault has occurred in this flow

I'm attempting to use a loop element in a flow I have created. My goal is to populate a custom lookup field on the Account record that looksup to the contact on the last closed opportunity. I'm not sure where my flow is going wrong, but when I select run, I get a message that there is an unhandled fault.

I have included an image of my flow below:

Update Accounts Flow

Thanks for the help!

Hi,

You can export the definition of your flow easily with a workbench so other people can analyze and even import it completely effortless.

1) Create this text file: packflow.xml with the content below (ie: c:\temp\packflow.xml) (very easy)

<?xml version="1.0" encoding="UTF-8"?>
<Package xmlns="http://soap.sforce.com/2006/04/metadata">
<types>
<members>*</members>
<name>Flow</name>
</types>
<version>41.0</version>
</Package>

2) Connect to the workbench (production or sandbox) with the credentials of your used org (if needed) (very easy)

https://workbench.developerforce.com/login.php

3) Menu: migration > retrieve

4) Select the created file for the Unpackaged Manifest : packflow.xml and button: Next

5) Button: Retrieve

6) Link: Download ZIP File

7) Open the downloaded ZIP File and extract all the files.

8) Copy/paste here the content of the file: <your flow name>-<version>.flow

I will know everything (100%) of your flow definition. I can read all the details of your flow directly from the metadata definition.

An example of Declarative Metadata Definition is shown here at the bottom of the page:

Hi Alain! Thanks for getting back to me. I've followed the above steps and pasted below. I read through the error message I received after running the flow, and I have deduced the issue is that there are some opportunities that do not have an associated contact and that is causing an error. Do you have an idea of how to get around this?

Hi Brianna,

I can do the exact opposite operation called "deploy" with the workbench now.

And I have exactly your flow in my free developer org so I can test it directly if necessary.

I will let you know as soon as everything is clarified.

If I launch your flow directly, there is no error with my few opportunities.

You can also see the log of your workflow launching it with Developer Console open.

You have used a very large scope for the main Fast Lookup : all the accounts with Opportunity_Amount_Total__c > 0

You can do that in "theory" but that could exceed the governor limits.

What is the content of your log?

If you have a sandbox:

a) To open the Developer Console from Salesforce Classic:
Click Your Name.
Click Developer Console.

https://help.salesforce.com/articleView?id=code_dev_console_opening.htm&type=5
b) Run your flow
c) Select the tab: Logs (like above) and double-click where your see /flow/... in the Developer Console

I will continue to look at your imported flow but it could already be fine.
