Insert an nest json objects with Error ERROR: Can't map PGType with oid=-272646673 to Crate type

I’m using CrateDB 5.5.2, and I create a dynamic objects table nifi.nifi_provenance to store json objects. But I encounter error Can't map PGType with oid=-272646673 to Crate type when inserting some records.

cr> show create table nifi.nifi_provenance;

Hi,
Do you have a ConvertJsontoSQL step? how does it look like?

Hi @hernanc , I use ReplaceText to generate insert sql with the json content.

the generated sql looks like.

insert into nifi.nifi_provenance values ('{
    "schedule": {
        "organizer": "00061300",
		"schedule_id": "��Q",
        "start_time": 1716281100,
        "end_time": 1716288300,
        "attendees": [{"userid":"00057939"},{"userid":"00061300"}],
        "summary": "1",
        "description": 61746076\n",
        "reminders": {
            "is_remind": 1,
            "remind_before_event_secs": 900,
            "is_repeat": 0,
            "timezone" : "8"
        },
        "location": "903"
    },
    "agentid": 0
}');

Hi,
There is missing opening quotes on the value on this line:

"description": 61746076\n"
