API Post issue "TypeError: 'str' object is not callable"

[Larz60+]

your strings must be enclosed in single or double quotes.
here's a display routine that accesses all nodes of structure:

ipstructure = {'name': 'xxxx', 'ipv4_start': 'xxxx', 'ipv4_cidr': 'xx', 'ipv4_address_domain_id': 'xxxx', 'INFO-ipv4_address_domain_name': 'xxxx', 'ipv4_address_domain_range_id': 'xxxx', 'INFO-ipv4_address_domain_range_name': 'xxxxx', 'ipv4_allocation_template_id': 'xxxx', 'dhcp_relay_id': '', 'ipv6_start': 'xxxx::', 'ipv6_cidr': 64.0, 'ipv6_address_domain_id': 'xxxx', 'INFO-ipv6_address_domain_id': 'xxxxx', 'ipv6_address_domain_range_id': 'xxxxx', 'INFO-ipv6_address_domain_range_name': 'xxxxxx::/49', 'ipv6_allocation_template_id': 'xxxx', 'dhcpv6_relay_id': '', 'l2_vni_value': '', 'INFO-l2_vni_name': '', 'l2_domain_id': '', 'INFO-l2_domain_name': '', 'dns_domain_id': '', 'INFO-dns_domain_name': '', 'is_infoblox_synced': 'xxxx', 'is_private': 'xxxx', 'tenant_id': 'xxxx', 'INFO-tenant_name': 'xxxx', 'partition_id': 'xxxx', 'INFO-partition_name': 'xxxx', 'provider_id': 'xxxx', 'INFO-provider_name': 'xxxxx', 'consumer_id': 'xxxx', 'INFO-resp_consumer_name': 'xxxx', 'other_consumers': '', 'INFO-other_consumer_names': '', 'vlan_tag': 'xxxx', 'INFO-vlan_name': '', 'description': '', 'hashtags': '', 'discovery_organization_id': '', 'INFO-discovery_organization_name': 'xxxx', 'discovery_credential_id': '', 'INFO-discovery_credential_name': 'xxxx', 'discovery_scanner_id': '', 'INFO-discovery_scanner_name': 'xxxx', 'discovery_exclude_justification': 'xxxx', 'INFO-Comments-Notes': ''}

def display_dict(dictname, level=0):
    indent = " " * (4 * level)
    for key, value in dictname.items():
        if isinstance(value, dict):
            print(f'\n{indent}{key}')
            level += 1
            self.display_dict(value, level)
        else:
            print(f'{indent}{key}: {value}')
        if level > 0:
            level -= 1
