Issues with Find Versions of a document by path or GUID Action

Hi

We are currently running a MS Flow which looks into our Projectwise datasource for certain files via a Saved Search input and then simply delete them using the Execute WSG Request (being fed the GUIDs from the Saved search).

This was initially working but we then had issues with the documents in Projectwise which had versions. In that case the WSG Request is failing which stops the Flow.

That's where we looked into the Find Versions of a document by path or GUID and thought that this would solve all our problems. However all our attempts have failed so far, even with a Flow as simple as the one below:

. 

Are there any known issues with this action? We've also noticed that the Projectwise connection keeps on failing and we've had to re-create the connection many times to make sure the flow keeps on working

Thanks
