Restful Api secure/sendbatch not working

[grimnir52]

I sent a request to secure/sendbatch and got back a response with 200 ok and the batch id and message count, but messages aren't getting sent even though the secure/send works fine so does the http Api.
Here is the request:

{
"batch_config": {
"callback_url": "http://host.docker.internal:5053/api/sms/batchstatus",
"errback_url": "http://host.docker.internal:5053/api/sms/batchstatus"
},
"globals" : {
"dlr-level": 3,
"dlr": "yes",
"dlr-url": "http://host.docker.internal:5053/api/sms/deliver",
"dlr-method": "POST"
}
"messages": [
{
"to": [
"55555551",
"55555552",
"55555553"
],
"content": "Hello world !"
}
]
}

And I would also like to know if there is a big performance increase if I switch to the SMPP Api from the rest Api?

I used the docker-compose.restapi.yml to spin up the containers.
