Regex Expression Error

[RodrigoBiaggio]

Guys, I need help with a regex rule for a request attribute. I need to get an email. I've tried several ways and Dynatrace doesn't accept my rules. In Regex101 it's OK, I can capture what I need, but when I put it in Dynatrace, I get an error message.

I don't know how to configure it within Dynatrace. Can anyone help?

Thank you

Try this way, more generic:

addressingkey: ([^ ]*+)

Assuming you are using a space after the email
