Specter API access on Umbrel

Support and Troubleshooting
1

Trying to access the Specter Server API (installed at an Umbrel Node) using Python:

import requests
import json
url = 'http://umbrel.local:25441/api/v1alpha/token'
header = {
             "Content-Type": "application/json",
         }
data = {
             "jwt_token_description": "Test Specter API Token",
             "jwt_token_life": "30 days"
         }

response = requests.post(url, headers=header, data=json.dumps(data))

But getting the following response.text back:

'<!DOCTYPE html><html lang="en"><head><title>Umbrel</title>
<meta charset="utf-8"><meta http-equiv="X-UA-Compatible" content="IE=edge"><meta name="viewport" content="width=device-width,initial-scale=1">

<strong>We\'re sorry but Umbrel doesn\'t work properly without JavaScript enabled. Please enable it to continue.</strong>

</noscript><div id="app"></div><script src="/js/chunk-vendors.5ff0ba32.js"></script><script src="/js/app.ab94624e.js"></script></body></html>'

Any ideas how to access the API without going through Umbrel before-request filters?
