Description of the bug

This also breaks the loading spinner animation.

Steps to reproduce

use either nf-core launch or nf-core schema build

Expected behaviour

This shouldn't be logged at all

System

Nextflow Installation

• >=1.13.3

Additional context

Probably due to a change of the default logging level of the requests_cache package. Downgrading it to 0.5.2 removes the problem. This should have been fixed since 0.6.1 (nf-core/smrnaseq#74 (comment)), but I still got the error using 0.6.2. Adding log.setLevel(logging.DEBUG) in utils.py, schema.py or launch.py, didn't resolve this problem.
