How to get Error Message and Status ?

How to get Error Message and Status ?

Hello,

In a flow, I'm creating an Invoice. In case there is an error, I trigger an cliq message to notify a bot with the error



However, editing the Message to Bot block, I can't find the Error Message variable in the Create invoice variable list (it's quite long list). How should I get these message to be available in the field ? What I should look for variable name ?



Regards
