No workflow email was sent because 'To', 'CC', 'BCC' are all empty

[Guillermo]

My app is not deployed, but I’m sending the report with the “Run” button. On “Send to:” is an expression [Key column].[Email column] of the table set for the report. But it returns the following error:

Properties:

“AppTemplateVersion”: “1.000325”,

Can someone help me with this?

Thanks in advance!
