[GitHub] [beam] damccorm opened a new issue, #19848: Beam transforms declared inside a method fail to pickle.
damccorm opened a new issue, #19848:
URL: https://github.com/apache/beam/issues/19848
```
from apache_beam.internal import pickler
class Outter():
def method(self):
class InnerA(object):
def __init__(self):
pass
class InnerB(InnerA):
def __init__(self):
super(InnerB,
self).__init__()
o = InnerB()
pickler.loads(pickler.dumps(o))
c = Outter()
c.method()
```
fails with
```
RuntimeError: maximum recursion depth exceeded while getting the str of an object
```
Workaround: declare the transforms on the module level.
