X_METER_INVALID
Means
an action's meter cannot be counted against
Typical cause
a meter: block declares a bad name, period or warnAt, warnAt without onWarn, or its limit resolved to something other than a whole number of 0 or more
Fix
meter: { name: 'calls', period: 'day', limit: ({ ctx }) => 500, warnAt: 0.8, onWarn: quotaWarning } — edit the action the cause names
