Creating a Document Set in SPOL Using Power Automate

I’m pretty close to getting this done but the final challenge seems to be that I can’t use dynamic content from a SPOL library as part of the create DocSet action.  From what I can see when using the Output function everything looks right and if I manually type in an ID number to be used it creates the DocSet as desired. Apparently it has something to do with using dynamic content…which is a must.  Any help is solving this issue would be most appreciated as I have several of these to create.  Images inserted.
