Airtable > PandaDoc: Fields show up as [fields__Email] instead of the value?

I have a Zap to create contracts from project records in an Airtable base. While creating the Zap, the email output is correct, showing “”, but when I send it through PandaDoc, I get:


“The app returned “validation_error”


And it looks like Zapier is sending through the email as “fields__Email” instead of the email address itself:



I hardcoded the email and the document went through just fine. Any guesses on why dynamic values for the “Client” email isn’t working?

Hi @jamesvclements!

The fact that it says fields__Email leads me to believe that the field you’ve mapped there perhaps has the email addresses as line items within that fields__Email array, rather than being the actual email address field.

Any chance you could share a screenshot of what that trigger step’s output looks like?

Thanks @nicksimard!


I ended up working this out. The field was mapped fine, but when the PandaDoc step failed for a different reason, it showed the output as `fields__Email` instead of the actual email address, even though that was being passed in the request. 


The PandaDoc step failed because I was using the same email address (my own for testing) for both parties I was passing to the document template - when I switched to a separate email for the Provider & Client parties, it worked :)
