Assigning allowedaddresspair to port is failing with openstack4j library

[sachin234s]

Hi,

We are using openstack4j-core-3.10.jar to call openstack api's. We are facing below issue when trying to associate allowedaddresspair to created port

2024-10-17 13:26:06,174 ERROR [com.hp.usage.vnfm.lcm.workflow.task.InstantiateVdu] [ThreadPoolOperationExecutorService-Thread-6] InstantiateVdu has failed. Cannot update read-only attribute created_at

The steps to recreate are as below

1. Create vip port is successful
2. create fixed ip port is successful
3. above issue is observed when fixedipaddress is updated by passing allowed address pairs in update.

Could you suggest how the above use case can be acheived without error?
