Trying to import a zip with a child assignment that was removed will result in Could not find assignment-data.json in zip-file. However, this message is confusing as it is referring to the child assignment’s assignment-data.json file, not the incorrect parent file. So it should be along the lines of:

Could not find my-child-assignment/assignment-data.json in zip-file
