When you want to deploy CPE 5.5.12 within a WebSphere Application Server 8.5.5 environment your will receive the issue that the WAS node cannot be fetched in the deployment task

This issue occurs because WAS 8.5.5 only supports Phyton 2.1 but the script is running in Phyton 2.2.2 specifiaction. To solve it you need to modify the fetchNodes.py under ContentEngine/tools/configure/scripts

Replace the content of the file with the following script.

def lstrip(value, chars=None):
if chars is None:
chars=' \t\n'
while value and value[0] in chars:
value = value[1:]
return value

node_list_str = AdminTask.listNodes()
node_names = [lstrip(s.strip()) for s in node_list_str.splitlines() if s.strip()]
regular_strings = [str(s) for s in node_names]
print regular_strings

Now the deployment task can fetch the WAS node and you can deploy the CPE 5.5.12
