Cannot set flushEnabled to true without setting the ramQuotaMB for a bucket through the REST api

For example:

To enable flushall on a bucket, the curl command I used:

curl -X POST -v -u Administrator:password -d "flushEnabled=1" http://10.3.2.55:8091/pools/default/buckets/default?bucket_uuid=3e0057a069f2007cf89265dd6a673500

.. throws an error:

• About to connect() to 10.3.2.55 port 8091
• Trying 10.3.2.55... connected
• Connected to 10.3.2.55 (10.3.2.55) port 8091

  {"errors": {"ramQuotaMB":"RAM quota cannot be set below current usage."}

  ,"summaries":

  }

However, if I set the ramQuotaMB to what it was along with flushEnabled, I'm able to enable flush:

curl -X POST -v -u Administrator:password -d "flushEnabled=1" -d "ramQuotaMB=4789" http://10.3.2.55:8091/pools/default/buckets/default?bucket_uuid=3e0057a069f2007cf89265dd6a673500
