MITRE ATT&CK Data - Custom STIX Types Not Supported

[kodebrain]

ver: 6.2.12

Hi, I ran into this issue while trying to ingest data from the MITRE ATT&CK framework. It seems the errors relate to custom STIX object types that are not supported by OpenCTI. ref: https://github.com/OpenCTI-Platform/connectors/tree/master/external-import/mitre

Error Message: Variable "$input" got invalid value "custom-type--1234abcd-56ef-78gh-90ij-klmnopqrstuv" at "input.toId"; Expected type "StixRef". Provided value custom-type--1234abcd-56ef-78gh-90ij-klmnopqrstuv is not a valid STIX ID (type custom-type not supported).

{ "type": "relationship", "id": "relationship--abcd1234-ef56-7890-gh12-ijklmnopqrst", "created": "2023-08-01T12:34:56.789Z", "relationship_type": "targets", "source_ref": "attack-pattern--abcd1234-ef56-7890-gh12-ijklmnopqrst", "target_ref": "custom-type--1234abcd-56ef-78gh-90ij-klmnopqrstuv", "description": "Example relationship between an attack pattern and a custom object." }

Thanks
