Hello,

I have integration working fine between syslog-ng v3.38 and MongoDB v6. I am working to enable MongoDB Time-Series Collections on a testing DB for the purpose of having better efficiency and improved queries over time.

I created the DB and collection, tested it by Mongo Compass client, then I tried to send the data from syslog-ng but it didn't work. MongoDB is throwing the following error:

"17:12:57. 483 | [2023-08-06T17:12:57.355549] Failed to insert into MongoDB; time_reopen='10', reason='\'datetime\' must be present and contain a valid BSON UTC datetime value', driver='d_mongodb_ttl#0"

destination d_mongodb_ttl {
        mongodb(
        uri("mongodb://192.168.1.19:27017/syslog-ng_ttl")
        collection("logs")
        value-pairs(
        scope("selected-macros")
        exclude("SOURCEIP")
        exclude("TAGS")
        pair("datetime" "${S_ISODATE}")
        pair("privateip" "${privateip}")
        pair("publicip" "${publicip}")
        pair("publicportrange" "${publicportrange}")
        pair("portaction" "${AI}")
        pair("portstatus" "${AL}")
        pair("host" "${HOST}"))
        );
};

Appreciate your help
