Config json_lines format separator on FluentBit HTTP Output, is it possible?

[canob]

Hi everyone,
I'm trying to send DNS log events from FluentBit to eKuiper (https://ekuiper.org/, a really cool project to add more stream processing capabilities to FluentBit), and having problems with the HTTP Output format of FluentBit.
eKuiper don't support JSON arrays in it HTTP Push Source, so I tried json_lines and json_stream formats, but with both, processing a file of 100 JSON lines of logs of DNS with FluentBit, I only receive the first event in eKuiper. Is like eKuiper cannot "detect" or "understand" the separator that FluentBit is using between JSON lines (if there is any, in a tcpdump I don't see any separator).
So, my question is, is there a way to configure what separator FluentBit is going to use between each JSON map/line when you use json_lines format on FluentBit HTTP Output?
Other option is to use a MQTT Broker and a eKuiper MQTT Source but for that, there is no MQTT Output in FluentBit (only a feature request, #674), and in that case I need to add Fluentd to the equation and create a pipeline like this one:
FluentBit Forward Output -> Fluentd MQTT Output -> MQTT Broker -> eKuiper MQTT Source
And is obviously more complicated and I need more resources, so I prefer to find the way of send logs from FluentBit HTTP Output to eKuiper HTTP Push Source.
Thanks in advance for your help.

Does anybody have an example/doc with the detail of the http body for each of the formats of HTTP Output?

Answering myself, and thanks to https://github.com/socsieng/capture-proxy, attached all the requests of FluentBit and the responses of eKuiper using the four formats of FluentBit HTTP Output: msgpack, json, json_stream, json_lines.
The tree events that I send on every test:

{"qname":"comm-cohort.ess.apple.com","source_ip":"10.11.21.7","timestamp":"Nov  2 10:38:05","tag":"dns_query","query_type":"A"}
{"qname":"roaming.officeapps.live.com","source_ip":"10.199.0.145","timestamp":"Nov  2 10:38:05","tag":"dns_query","query_type":"A"}
{"query_type":"A","timestamp":"Nov  2 10:38:05","tag":"dns_query","source_ip":"10.11.0.50","qname":"ntp.msn.com"}

With that, you can see exactly how FluentBit constructs every format.
