…without callback When stream=true and no callback is provided, _execute() would call callback(null, result) on the undefined callback, throwing TypeError. Guard the callback in _execute() so a no-op is used when no callback is provided, allowing stream consumers to receive results via events on the returned Request object.

Summary
Fixes a
TypeError: callback is not a functionthat occurs when callingps.execute(values)withps.stream = trueand no callback provided.Root Cause
In
_execute(), the innerreq.execute('sp_execute', callback)unconditionally callscallback(null, result)on completion — but when streaming without a callback,callbackisundefined.Fix
Guard the callback parameter in
_execute()so a no-op function is used when no callback is provided. This allows stream consumers to receive results viarow/error/doneevents on the returned Request object, consistent with howRequest.query(),Request.batch(), andRequest.execute()handle streaming.Test
Added a unit test that verifies
ps.execute({})does not throw whenstream = trueand no callback is given. The test confirms the TypeError regression on master and passes with the fix.Closes #1848
