Issues with attaching PDF file emailed from O365 to CRM (ClarityCRM)

I am trying to have an invoice sent from QBO attach to an account in Clarity.  Technically it is a ZAP between Outlook and Clarity

Here is my Zap:

1, Trigger: New email is received by a specific outlook account used by QBO and has a CC email address in the format of (Account#@domain.com- fake email address)

2. Filter: only continue if email subject contains, Invoice, Paid Invoice, PO

3. Remove domain from CC email. 

4. Look up the account using the value from #3(#4 & #5 are not both needed)

5. Look up the account using the value from #3 (#4 & #5 are not both needed)

6. Confirm the attachment and prepare it to be uploaded.

7. Upload the attachment to the account

Here is my step 6:

And says it is working (Test was successful!)

Here are my commands in step 7:

When I use this the upload fails:

Clarity says:

{

                " APIKey": "purefiltration-key-XXXXXXXXXXXXXXXXXXXXXX",

                "Resource": "Attachment",

                "Operation": "Create",

                "Data": {

                                "Name": "{{103964163__subject}}.pdf",

                                "Title": "{{103964163__subject}}

                                "SourceObjectId": "{{103964166__AccountId}}",

                                "SourceObjectType": "Account",

                                "FileContent": "{{103964167__data}}"

                }

}

I think it worked when I use this upload:

{

                "APIKey": "purefiltration-key-XXXXXXXXXXXXXXXXXXXXXX",

                "Resource": "Attachment",

                "Operation": "Create",

                "Data": {

                                "Name": "{{103656557__subject}}.pdf",

                                "Title": "{{103656557__subject}}",

                                "SourceObjectId": "{{103961482__Data[]AccountId}}",

                                "SourceObjectType": "Account",

                                "FileContent": "{{103964007__data}}"

                }

}

However I do not know where to find the Data[]AccountId}}",   to make this work.

Any advice on why the emailed attachment is not uploading to the CRM?  Is there a different way I should be doing this.  I am a novice at this stuff and blindly finding my way through this.
