Cannot use "Created by" from Azure DevOps as a valid receiver in "Send an Email" action

[mariliu]

I want to send an email to a user who creates new Azure DevOps work item. However, by using "Created by", the flow does not work. It seems that flow cannot recognize the "Created by" as a valid email address. 

I have tried different actions, including "send an email", "send an email (V2)". Same issue. 

Part of my flow

Hi @mariliu ,

I did a test on my side. Created By contains not only the email address, but also the Display Name of the user.

Like:

You coule use the Expression below to remove extra parts and leave a valid email address.

Expression reference:

replace(last(split(triggerBody()?['fields']?['System_ChangedBy'],'<')),'>','')

Please take a try again.

Thank you! Although I don't understand that expression, I just copied and pasted your reference into my Flow, and it worked. Appreciate your answer, Barry!
