Tunnel Token parsed incorrectly

[mrchi]

Here's the agent container config screenshot. the tunnel token is incorrect and it's a json string now.

Hi @mrchi,
Thanks for the PR and for bringing this to my attention!

I've investigated this on my end. When I test the tunnel token retrieval (even by completely removing the existing tunnel in Cloudflare, deleting the Docker image and state.json, and starting a fresh DockFlare instance), my instance correctly fetches the raw token string directly from the Cloudflare API endpoint (/accounts/.../cfd_tunnel/.../token). This means the cloudflared agent starts correctly with the raw token, not a JSON string.

The evidence you provided in issue #46 (the Cmd array showing a JSON string for the token) is very clear, so something is definitely different in how the token was obtained or processed in that scenario.

A few thoughts and questions to help us narrow this down:

• API Response Variation: It's possible Cloudflare's API might be returning different formats for this specific token endpoint to different users/regions, or it might have been a temporary behavior.
• Local Environment: Could there be anything in your specific setup (e.g., custom scripts, environment variables that might alter API interaction, or even a proxy if you're using one) that might cause the API response to be interpreted or wrapped as JSON before DockFlare's get_tunnel_token_via_api function processes it?

for debug:

# Temporary debug code within get_tunnel_token_via_api,

import requests
import json

CF_API_TOKEN = "your_actual_token" # From your .env
CF_ACCOUNT_ID = "your_account_id" # From your .env
TUNNEL_ID_TO_TEST = "an_existing_tunnel_id" # From your CF dash or your app's state

endpoint_url = f"https://api.cloudflare.com/client/v4/accounts/{CF_ACCOUNT_ID}/cfd_tunnel/{TUNNEL_ID_TO_TEST}/token"
headers = {
    "Authorization": f"Bearer {CF_API_TOKEN}",
    "Content-Type": "application/json", # Usually included, though for a GET token, maybe not strictly needed by CF
}

try:
    response = requests.get(endpoint_url, headers=headers, timeout=10)
    response.raise_for_status() # Check for HTTP errors

    print(f"Status Code: {response.status_code}")
    print(f"Content-Type Header: {response.headers.get('Content-Type')}")
    print("Raw Response Text:")
    print(response.text)

    print("\nTrying to parse as JSON:")
    try:
        json_data = response.json()
        print("Successfully parsed as JSON:")
        print(json.dumps(json_data, indent=2))
    except json.JSONDecodeError:
        print("Failed to parse as JSON. Response is likely raw text.")

except requests.exceptions.RequestException as e:
    print(f"Request failed: {e}")
    if e.response is not None:
        print(f"Response content on error: {e.response.text}")
