how to concatenate string with triggerbody?

Question

I've been attempting to concatenate:

@{concat('/',parameters('embedAttachmentsContainerDone'),'/','/@{triggerBody()?[''Properties'']?[''DestinationFileName'']})}

I've also tried:

@concat('/',parameters('embedAttachmentsContainerDone'),'/','/@{triggerBody()?[''Properties'']?[''DestinationFileName'']})

Sometimes I will get a deploy error, other times I'm getting an error while running the logic app. Other times, I am getting a very weird message:

@{concat('/',parameters('embedAttachmentsContainerDone'),'/',triggerBody()?['Properties']?['DestinationFileName'])}

How do we concatonate a string, with a parameter, with triggerBody?

Answer 1

You may have a try with this expression:concat('/',parameters('embedAttachmentsContainerDone'),'/@{triggerBody()?[''Properties'']?[''DestinationFileName'']'). In the third expression which you shared above, please use '' in front of Properties and behind the Properties, and put /@{triggerBody()?[''Properties'']?[''DestinationFileName''] in a pair of single quotes.
