Task 4788 is broken - Githubissues

When I try downloading the task in R I get:

> tsk <- getOMLTask(task.id = 4788)
Task '4788' file 'task.xml' found in cache.
Task '4788' file 'datasplits.arff' found in cache.

There appear to be similar problems in python.

Python input:

import openml
t = openml.tasks.get_task(4788)

output:

During handling of the above exception, another exception occurred:
