Problem with the xml() cube method with new numpy=1.22 #4478
Description
📰 Custom Issue
Hey guys, we are seeing this when trying to access the cube.xml() method of a certain cube (picked up by CI tests here and reproduced locally, of which the output below is from) with the new numpy=1.22, otherwise 1.21.x works no problemo:
so when trying to access cube.xml() method:
