Acknowledgements

• I have searched (https://github.com/utmstack/UTMStack/issues) for past instances of this issue
• I have verified that my UTMStack version is up-to-date

Describe the bug

We installed UTMStack v10.9.4 on one instance and v11.2.6 on a separate instance. We identified an issue with the JSON Inputs integration that prevents log forwarding on the newer version, even when using the examples provided in your documentation.

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

The /v1/logs endpoint should accept POST requests containing a JSON array of log entries and return a 200 status with {"status":"received"}, as it currently does on v10.9.4. Both versions should behave consistently when receiving logs through the JSON Inputs integration, regardless of the payload content or log source configuration.

Current Behavior

On v11.2.6, the same POST request to /v1/logs returns a 404 page not found error, indicating the endpoint is either missing, renamed, or no longer exposed on the expected port. No logs are ingested, and no additional error details are provided in the response body.

Reproduction Steps

Send logs using Python requests library

import requests
import json

Define the URL

url = "https://site1.selfsign:8080/v1/logs"
logs = [] # Replace with your actual log data
payload = json.dumps(logs)

Define headers

headers = {
'Utm-Connection-Key': 'Connectionkey==',
'Utm-Log-Source': 'your log source (mandatory header)',
'Content-Type': 'application/json'
}

Make a POST request

response = requests.request("POST", url, headers=headers, data=payload)

Print the response

print(response.text)

Possible Solution

No response

Additional Information/Context

Below are the terminal outputs from both instances for comparison:

v10.9.4 — site2.selfsigndsite (working)
