limit query apply_strategies

[Zhou Li]

When i use python, the error occured. My query is:

g.V(14012536).as_('start').repeat(__.timeLimit(2000).both()).until(__.loops().is_(1)).dedup().as_('a').limit(__.select('a').hasId(288854240, 295903304, 290861088).count().map(lambda: ("it.get()", "gremlin-groovy")).toList()).toList()

Error detail: 

  File "xxx\lib\site-packages\gremlin_python\process\traversal.py", line 57, in toList
    return list(iter(self))
  File "xxx\lib\site-packages\gremlin_python\process\traversal.py", line 47, in __next__
    self.traversal_strategies.apply_strategies(self)
AttributeError: 'NoneType' object has no attribute 'apply_strategies'

Can anyone tell me how to fix the error.

I'm not sure but you have a embedded toList() on an anonymous traversal:

map(lambda: ("it.get()", "gremlin-groovy")).toList()

that toList() is causing the anonymous traversal to iterate and i'd imagine that causes the failure?

not the anonymous traversal problem, the query like this already has problem, and the two query in gremlin client has no problem.

g.V(14012536).as_('start').repeat(__.timeLimit(2000).both()).until(__.loops().is_(1)).dedup().as_('a').limit(__.select('a').hasId(288854240, 295903304, 290861088).count().toList()).toList()
