I've been using the yahoo price source successfully up until two days ago. Beancount hasn't been updated, so it must be something with the API. I couldn't find anything on the yahoo website, so wanted to check here if others are getting an error too.
The command and error are:
bean-price -e "USD:yahoo/SCHA"
ERROR : Error fetching SCHA: Expecting value: line 1 column 1 (char 0)
ERROR : Could not fetch for job: DatedPrice(base='SCHA', quote='USD', date=None, sources=[PriceSource(module=<module 'beancount.prices.sources.yahoo' from '/usr/lib/python3.9/site-packages/beancount/prices/sources/yahoo.py'>, symbol='SCHA', invert=False)])
