Send an email (v2) - sometime mails are sent with only recipient in BCC, sometime not

Hello!

I've noticed a strange behavior in one of my flows. I have a flow that is triggered every day at the same time and iterates over a Dataverse table. This table contains the email addresses for the "To" and "CC" recipients, which are used in the subsequent "Send an Email (v2)" action.

Based on certain filters, the "Send an Email (v2)" action is triggered using the output from the Dataverse table. However, sometimes the filter matches, but the email address fields are empty, causing the "To" and "CC" fields to remain unfilled. The "BCC" field, on the other hand, is always populated via a variable.

Now, we are experiencing inconsistent behavior:

  • In some cases, emails are sent successfully to the BCC recipient, even though the "To" and "CC" fields are empty.

  • In other cases, the flow fails with the following error message:

    "status": 400, "message": "Parameter 'To' cannot be null or empty."

Strangely, on the next execution of the flow, the same Dataverse entry that previously failed is successfully sent to the BCC recipient.

Does anyone have any ideas why we are experiencing this random behavior?

Thank you for your help!

    if you are using the Column format "Email "Make sure you treat the email columns as Text Format.
