Thank you so much for this response! So I did find a fix (with what I posted and your Option B!)

Option A: Didn't work. Surprisingly I used a ML Single User cluster for everything in my job and this wasn't a fix in my case - it still triggered this error.

Option B: Is exactly the route I ended up taking (I had a similar response for people to see/comment on) and I am glad you mention this because is defiantly worked!

Thanks for confirming and for others Option B is the way!
