# Debug Logging for CI Test Failures
2+
3+
## Overview
4+
5+
Extensive debug logging has been added to help diagnose the credential test failures in CI environments. The logging is automatically enabled when `NODE_ENV=test` or when running in CI (`process.env.CI` is set).
6+
7+
## What's Been Added
8+
9+
### 1. Test File Logging (`tests/credentials.test.ts`)
10+
11+
Each failing test now logs:
12+
- Input `apiTokenIssuer` value
13+
- Expected URL that should be requested
14+
- Parsed URL components (protocol, hostname, host, port, pathname, search)
15+
- Nock setup details (baseUrl, path, full mock URL)
16+
- Active nock interceptors before and after scope creation
17+
- Request success/failure status
18+
- Scope completion status
19+
- Remaining/pending mocks
20+
21+
**Example output:**
22+
```
23+
=== Token Refresh Test Debug Info ===
24+
Input apiTokenIssuer: issuer.fga.example
25+
Expected URL: https://issuer.fga.example/oauth/token
26+
Parsed URL details:
27+
- protocol: https:
28+
- hostname: issuer.fga.example
29+
- host: issuer.fga.example
30+
- port:
31+
- pathname: /oauth/token
32+
- search:
33+
Nock setup:
34+
- baseUrl: https://issuer.fga.example:443
35+
- path: /oauth/token
36+
- full mock URL: https://issuer.fga.example:443/oauth/token
37+
Active nock interceptors: []
38+
Nock scope created, active mocks: [ 'POST https://issuer.fga.example:443/oauth/token' ]
39+
```
40+
41+
### 2. Credentials Service Logging (`credentials/credentials.ts`)
42+
43+
The `buildApiTokenUrl` method logs:
44+
- Input `apiTokenIssuer`
45+
- Normalized URL (after adding https:// prefix)
46+
- URL object details (protocol, hostname, host, port, pathname, search)
47+
- Final URL returned by `url.toString()`
48+
49+
The `refreshAccessToken` method logs:
50+
- The URL being requested
51+
- HTTP method
52+
- Request payload keys (without sensitive values)
53+
54+
**Example output:**
55+
```
56+
[Credentials.buildApiTokenUrl] Debug info:
57+
Input apiTokenIssuer: issuer.fga.example
58+
Normalized: https://issuer.fga.example
59+
URL object details:
60+
- protocol: https:
61+
- hostname: issuer.fga.example
62+
- host: issuer.fga.example
63+
- port:
64+
- pathname: /oauth/token
65+
- search:
66+
Final URL (toString): https://issuer.fga.example/oauth/token
67+
68+
[Credentials.refreshAccessToken] About to make request:
69+
URL: https://issuer.fga.example/oauth/token
70+
Method: POST
71+
Payload keys: [ 'client_id', 'client_secret', 'audience', 'grant_type' ]
72+
```
73+
74+
### 3. HTTP Request Logging (`common.ts`)
75+
76+
The `attemptHttpRequest` function logs:
77+
- Request URL
78+
- HTTP method
79+
- Base URL (if set)
80+
- Request headers
81+
- Success/failure status
82+
- Error details (code, message, response status)
83+
84+
**Example output:**
85+
```
86+
[attemptHttpRequest] Request config:
87+
URL: https://issuer.fga.example/oauth/token
88+
Method: POST
89+
BaseURL: undefined
90+
Headers: {
91+
"Content-Type": "application/x-www-form-urlencoded"
92+
}
93+
[attemptHttpRequest] Request succeeded!
94+
```
95+
96+
## Key Insights from Logs
97+
98+
The logs reveal the core issue:
99+
100+
1. **Nock mock URL**: `https://issuer.fga.example:443/oauth/token` (with explicit port)
101+
2. **Actual request URL**: `https://issuer.fga.example/oauth/token` (without port)
102+
103+
This mismatch occurs because:
104+
- Node.js's `URL.toString()` omits default ports (443 for HTTPS, 80 for HTTP)
105+
- In CI environments, the HTTP client or interceptor includes the port explicitly
106+
- This causes nock's URL matching to fail
107+
108+
## Using the Logs
109+
110+
When tests fail in CI:
111+
112+
1. Look for the log sections marked with `===` or `[MethodName]`
113+
2. Compare the "Nock setup" URL with the "Final URL (toString)"
114+
3. Check the "Active nock interceptors" to see what nock is expecting
115+
4. Compare with the actual request being made in `[attemptHttpRequest]`
116+
5. Look for any "NetConnectNotAllowedError" messages to see what URL nock couldn't match
117+
118+
## Next Steps
119+
120+
Based on the CI logs, we can:
121+
1. Determine if the issue is port-related (default ports being included/excluded)
122+
2. See if there are differences in how URLs are constructed between local and CI
123+
3. Adjust the nock matching strategy accordingly
124+
4. Consider using more flexible nock matchers if needed
125+
126+
## Cleanup
127+
128+
Once the issue is resolved, you can:
129+
1. Remove the debug logging by reverting changes to:
130+
- `tests/credentials.test.ts`
131+
- `credentials/credentials.ts`
132+
- `common.ts`
133+
2. Or keep minimal logging for production debugging (guard with `process.env.DEBUG`)
134+
