Mirror Between document libraries based off Choice Column

Update to this seeing as no one seems to know how to help:

As there might be someone looking for this in the future I'll include the solution here.

Good luck stranger, google is your friend!

I resolved it myself with the following flow structure:

• I needed to use the following expressions for the folder path in Copy File step:

take(triggerOutputs()?['body/{Path}'],sub(length(triggerOutputs()?['body/{Path}']),1))

• Made sure that the create folder step only runs if the folder is not present, and a join with a split function in the expression to take the file path without the root document library folder part and join it again:

join(skip(split(triggerOutputs()?['body/{Path}'],'/'),1),'/')

Then the copy file runs again and copies into the created folder.

The issue with my trigger condition was that I included spaces once I removed them it worked perfectly:

@equals(triggerBody()?['ExternalSharingDocuments']?['Value'],'Shared')

Finally, I will create a separate delete flow for any "Shared" documents deleted in the source library to delete them in the document portal.

Hope this helps someone.
