Description

We can set invalid date/time values using pycti module in a python program, but then we cannot read or modify this value because an error is raised when accessing it

Environment

1. OS: Ubuntu 22.04 LTS
2. OpenCTI version: 6.6.6
3. OpenCTI client: python

Reproducible Steps

1. Execute this code:

# 5ad3865a-abd0-4f51-b4b4-e8a12a8481dd is the id of an existing intrusion_set

api_client.stix_domain_object.update_field(
    id="5ad3865a-abd0-4f51-b4b4-e8a12a8481dd", input={"key": "first_seen", "value": "2025-04-30"}
)

2. Everything seems ok, BUT
3. If we open this url in a browser

https://opencti-cti.gfor.ses-op/dashboard/threats/intrusion_sets/5ad3865a-abd0-4f51-b4b4-e8a12a8481dd

the following error appears:

(!) An unknown error occurred. Please provide a [support package](https://opencti-cti.gfor.ses-op/dashboard/settings/support) to your administrator or OpenCTI maintainers

Expected Output

I expect that "stix_domain_object.update_field" function does not allow to set bad date / time values or that internal checks within openCTI code do not allow to assign invalid date / time values

Actual Output

An invalid date/ time value is stored and an error occurs when trying to read this wrong value
