After failure, getting error message and putting into email body.

[Solomon1]

After run this action "Run a flow built with Power Automate Desktop"

when it fails, its output contains "message: ..." and I want to include the error message into email body for debugging purposes.

It would be much appreciated in advance for your step by step explanation for a newbie like me.

Hi @Solomon1,

You can configure a run after when it has failed (which by looking at your screenshot you have already configured) and then use the following expression:

outputs('NameofYourAction')?['body']['error']['message']
