Error: Invalid/No state provided

[net47]

So I have a single-nic-deployment of a BIG-IP 14.1.0.6, trying to get stats to a StatsD instance on a different host.

My Procedure:

1. installing BigStats on BIG-IP
   curl -u root:SuperSecretPW -X POST http://localhost:8100/mgmt/shared/iapp/package-management-tasks -d '{ "operation":"INSTALL","packageFilePath": "/var/config/rest/downloads/BigStats-0.5.1-0012.noarch.rpm"}'

2. configuring BigStats on the BIG-IP
   curl -u root:SuperSecretPW -X POST http://localhost:8100/mgmt/shared/bigstats_settings -d '{"config":{"destination":{"protocol": "statsd","address": "1.1.1.1","port": 8125},"size": "large","interval": 2, "enabled": true, "debug": false}}'

After the second command, I get the following error message:
{"code":500,"message":"[BigStats] - Error: Invalid/No state provided...","referer":"Unknown","originalRequestBody":"\"{\\\"config\\\":{\\\"destination\\\":{\\\"protocol\\\": \\\"statsd\\\",\\\"address\\\": \\\"1.1.1.1\\\",\\\"port\\\": 8125},\\\"size\\\": \\\"large\\\",\\\"interval\\\": 2, \\\"enabled\\\": true, \\\"debug\\\": false}}\"","errorStack":[]}

Firewall is completely open. Am I missing something in the configuration?

Edit: IP's of both instances are public IPs, for this issue I changed them to 1.1.1.1

Hello. Likely the schema validation is failing for the given configuration. Specifically, the "interval" value does not meet the required minimum of 10. Can you please change this value and try again?

Here's the schema of the version you are using in case you find that you need it.

What happens when you add the following to your curl command:

-H "Content-type: application/json"
