Demystifying iControl REST Part 7 - Understanding Transactions

I'm working on a python script which needs to create a LTM policy with 1 condition and 2 corresponding actions. Creating the policy and empty rule works like a charm but when I try adding the condition and actions in a transaction it fails.

def updatePolicy(partition, policyName, serverName, virtualServerName, env):
    pol = ''
    cCondition = {
        u'name': u'0',
        u'fullPath': u'0',
        u'index': 0,
        u'all': True,
        u'caseInsensitive': True,
        u'equals': True,
        u'external': True,
        u'httpHost': True,
        u'present': True,
        u'remote': True,
        u'request': True,
        u'values': [serverName]
    }
    cAction1 = {
        u'name': u'0',
        u'fullPath': u'0',
        u'forwards': True,
        u'request': True,
        u'select': True,
        u'virtual': u'/{0}/{1}'.format(partition, virtualServerName),
    }
    cAction2 = {
        u'name': u'1',
        u'fullPath': u'1',
        u'disable': True,
        u'request': True,
        u'serverSsl': True,
    }
    try:
        pol = mgmt.tm.ltm.policys.policy.load(name=policyName, partition=partition)
        pol.draft()
    except Exception as e:
        try:
            pol = mgmt.tm.ltm.policys.policy.load(name=policyName, partition=partition, subPath='Drafts')
            print("...loaded policy draft")
        except Exception as ee:
            try:
                pol = mgmt.tm.ltm.policys.policy.create(
                    name = policyName,
                    subPath = 'Drafts',
                    partition = partition,
                    ordinal = 0,
                    strategy = 'first-match',
                    controls = ["forwarding","server-ssl"],
                    requires = ["http"]
                )
                print("...created policy")
            except Exception as eee:
                print(eee)
                sys.exit(1)
    
    print("...adding rule to policy {0}".format(pol.name))
    rules = pol.rules_s.get_collection()
    
    rule = pol.rules_s.rules.create(
        name = "rule-{0}".format(serverName),
        subPath = 'Drafts',
        ordinal = 0,
        description = 'Redirect to /{0}/{1}'.format(partition, virtualServerName)
    )
    # Incorrect URI path must be corrected else setting condition won't work
    rule._meta_data['uri'] = pol._meta_data['uri'] + 'rules/rule-{0}/'.format(serverName)
    tx = mgmt.tm.transactions.transaction
    with TransactionContextManager(tx) as api:
        print("...add condition")
        rule.conditions_s.conditions.create(**cCondition)
        print("...add actions")
        rule.actions_s.actions.create(**cAction1)
        rule.actions_s.actions.create(**cAction2)
    print("...updating rule")
    rule.update()
    pol.publish()

The issue I'm facing is maybe connected to the actions being added to the rule. When I run the script I receive the following output (rule is deleted manually before each run):

...loaded policy draft
...adding rule to policy policy-test-001
...create rule
...add condition
...add actions

During handling of the above exception, another exception occurred:

If I comment out the second action additition rule.actions_s.actions.create(**cAction2) I receive the same error but this time rule.actions_s.actions.create(**cAction1).

If both action lines are removed from the code the policy is updated but with only the condition.

Are there any specific things I need to keep in mind when adding actions to a rule and how can I change the code so that it works?
