I think this is a bug introduced during the sdm refactorings, and I
also reproduced it once
but did not have time to investigate it yet.
If the code expect the replace a volume path during runtime, we should
have a setter:
@property
def volumePath(self):
return self._volumePath
@volumePath.setter
def volumePath(self, value):
self._volumePath = value
You can try add this to the manifest class and see if it fixes this issue.
Which class is it? Where is it located?
