Bojidar Marinov updated IGNITE-15266:
-------------------------------------
Description:
When reading an object that contains an object array directly inside another object array from python, and attempting to write it back directly, the following error is raised:
{code:java}
File ".../ignite-python-thin-client/pyignite/utils.py", line 69, in is_hinted
return isinstance(value, tuple) and len(value) == 2 and issubclass(value[1], IgniteDataType)
TypeError: issubclass() arg 1 must be a class
{code}
Sample reproduction:
{code:java}
from pyignite import Client
from pyignite.datatypes import ObjectArrayObject
ignite = Client()
with ignite.connect('localhost', 10800):
cache = ignite.get_or_create_cache('example')
example_nested = ((ObjectArrayObject.OBJECT, [1]), ObjectArrayObject)
example = (ObjectArrayObject.OBJECT, [example_nested])
print(example) # (-1, [((-1, [1]), <class 'pyignite.datatypes.complex.ObjectArrayObject'>)])
cache.put('example', example)
print(cache.get('example')) # (3, [(-1, [1])])
cache.put('example', cache.get('example')) # TypeError: issubclass() arg 1 must be a class
print(cache.get('example'))
{code}
