This flow is failing becuase for some reason the Send an Email V2 is thinking an attachment is required

I have 3-step flow

"SharePoint trigger" and "Outlook Send an email v2"

Flow

1.When a new response is submitted

- Form Id

2.Get Response details

- Form Id

- Response ID

3.Send an email (no attachment)

To* Your Email Address
Subject* New Subject
Body* some basic text with some Dynamics Content
CC* my email address
Attachments

Steps to fix
I modified the Flow and deleted the NULL attachment reference and resaved.

Error is

Action 'Send_an_email_(V2)' failed: Parameter 'Attachment Name' cannot be null or empty. clientRequestId: XXXXXXXX

Hey Mate,

You can simply add a condition screenshot below, if attachment existing send an email with attachment if it does not, just send an email without attachments.

Expression empty(<your attachment field name>)

I did a video for Microsoft Forms some time back you can find it here - https://www.youtube.com/watch?v=YDWpGW1BaBU
