FCPX > Resolve > FCPX XML Error

So I'm sending a project XML from FCPX to Resolve, grading it, then choosing the FCPX XML Round Trip from Resolve deliver page. It sends the clips and new XML file out to specified folder, and then i try to import that XML and FCPX gives me this error every time now...

Not sure whats going on here...It did work one time when i did it yesterday...dont know why it wouldn't now...

I'm using the Resolve 12 (beta) so maybe thats it...but it just seems like something is off now since it did actually work from Resolve back to FCPX yesterday...

Any tips?

Thanks

I'm doing the same workflow, also using the Resolve 12 beta (beta version 2) and will keep an eye out for this error.

The only time that happened to me before (with Resolve 11) sorted itself out after I rebooted the machine.
