Onenote debug bundle

OneNote Debug Bundle

Overview

When OneNote API calls fail, you need the request-id response header (Microsoft support requires it), decoded JWT token claims (to verify granted scopes), the x-ms-ags-diagnostic header (internal Graph routing info), and the full error body — all correlated to a single request. This skill generates structured diagnostic bundles for self-diagnosis and Microsoft support ticket filing.

Prerequisites

• Node.js 18+ or Python 3.10+
• An existing OneNote integration with Graph API calls
• @microsoft/microsoft-graph-client or msgraph-sdk installed
• Access token available (for token inspection)

Instructions

TypeScript Diagnostic Middleware

Intercept all Graph API calls and capture diagnostics automatically:

// src/debug/diagnostic-middleware.ts
interface DiagnosticEntry {
  timestamp: string; method: string; url: string; status: number;
  requestId: string | null; agsDiagnostic: string | null;
  retryAfter: string | null; duration_ms: number; error: any | null;
}

const diagnosticLog: DiagnosticEntry[] = [];

export function createDiagnosticMiddleware() {
  return {
    execute: async (context: any) => {
      const start = Date.now();
      const { url, method } = context.request || { url: "unknown", method: "GET" };
      try {
        await context.next();
        const h = context.response?.headers;
        diagnosticLog.push({
          timestamp: new Date().toISOString(), method, url,
          status: context.response?.status || 0,
          requestId: h?.get?.("request-id") || null,
          agsDiagnostic: h?.get?.("x-ms-ags-diagnostic") || null,
          retryAfter: h?.get?.("retry-after") || null,
          duration_ms: Date.now() - start, error: null,
        });
      } catch (err: any) {
        diagnosticLog.push({
          timestamp: new Date().toISOString(), method, url,
          status: err?.statusCode || 0,
          requestId: err?.headers?.["request-id"] || null,
          agsDiagnostic: err?.headers?.["x-ms-ags-diagnostic"] || null,
          retryAfter: err?.headers?.["retry-after"] || null,
          duration_ms: Date.now() - start,
          error: { code: err?.code, message: err?.message, body: err?.body },
        });
        throw err;
      }
    },
  };
}

export function getDiagnosticLog(): DiagnosticEntry[] { return [...diagnosticLog]; }
export function clearDiagnosticLog(): void { diagnosticLog.length = 0; }

Token Claims Inspection (No External Libraries)

Decode a JWT access token to inspect scopes and expiry using only built-in Base64:

// src/debug/token-inspector.ts
export function decodeTokenClaims(accessToken: string): Record<string, any> {
  const parts = accessToken.split(".");
  if (parts.length !== 3) throw new Error("Invalid JWT: expected 3 dot-separated parts");
  const base64 = parts[1].replace(/-/g, "+").replace(/_/g, "/");
  const padded = base64 + "=".repeat((4 - (base64.length % 4)) % 4);
  return JSON.parse(Buffer.from(padded, "base64").toString("utf-8"));
}

export function analyzePermissions(claims: Record<string, any>, required: string[]) {
  const granted = claims.scp ? claims.scp.split(" ") : (claims.roles || []);
  const missing = required.filter((s) => !granted.includes(s));
  const now = Math.floor(Date.now() / 1000);
  const isExpired = claims.exp < now;
  const diff = Math.abs(claims.exp - now);
  const expiresIn = isExpired ? `Expired ${diff}s ago` : `${Math.floor(diff / 60)}m remaining`;
  return { granted, missing, isExpired, expiresIn };
}

Python Diagnostic Context Manager

# debug/diagnostic_capture.py
import json, base64, time
from datetime import datetime, timezone
from dataclasses import dataclass, asdict
from typing import Optional

@dataclass
class DiagnosticCapture:
    timestamp: str; method: str; url: str; status: int
    request_id: Optional[str]; ags_diagnostic: Optional[str]
    retry_after: Optional[str]; duration_ms: float
    error_code: Optional[str]; error_message: Optional[str]

class GraphDiagnostics:
    def __init__(self):
        self.captures: list[DiagnosticCapture] = []

    async def capture_request(self, client, method: str, endpoint: str, **kwargs):
        url = f"https://graph.microsoft.com/v1.0{endpoint}"
        start = time.monotonic()
        try:
            response = await client.api(endpoint).get() if method == "GET" \
                else await client.api(endpoint).post(kwargs.get("body"))
            self.captures.append(DiagnosticCapture(
                datetime.now(timezone.utc).isoformat(), method, url, 200,
                None, None, None, round((time.monotonic()-start)*1000, 2), None, None))
            return response
        except Exception as e:
            headers = getattr(e, "headers", {}) or {}
            self.captures.append(DiagnosticCapture(
                datetime.now(timezone.utc).isoformat(), method, url,
                int(getattr(e, "status_code", 0)),
                headers.get("request-id"), headers.get("x-ms-ags-diagnostic"),
                headers.get("retry-after"), round((time.monotonic()-start)*1000, 2),
                str(getattr(e, "code", type(e).__name__)), str(e)))
            raise

    def export_bundle(self, filepath: str, token: Optional[str] = None) -> str:
        bundle = {"bundle_version": "1.0", "generated": datetime.now(timezone.utc).isoformat(),
                  "captures": [asdict(c) for c in self.captures]}
        if token:
            parts = token.split(".")
            bundle["token_claims"] = json.loads(base64.urlsafe_b64decode(parts[1] + "=="))
        with open(filepath, "w") as f:
            json.dump(bundle, f, indent=2)
        return filepath

Microsoft Support Ticket Template

When filing a support case, include this from the diagnostic bundle:

Subject: OneNote Graph API - [Error Code] on [Endpoint]

1. Request ID: [from request-id response header]
2. Timestamp (UTC): [from diagnostic bundle]
3. Tenant ID: [from token claims tid]
4. App ID: [from token claims azp]
5. Endpoint: GET /me/onenote/notebooks
6. HTTP Status: 403
7. Error Code: ErrorAccessDenied
8. Error Message: Access is denied.
9. x-ms-ags-diagnostic: [full header value]
10. Token scopes granted: Notes.Read User.Read
11. Expected scopes: Notes.ReadWrite
12. SDK version: @microsoft/[email protected]

Common Diagnostic Patterns

"Why is my 403 happening?" — Decode token, compare scopes:

const claims = decodeTokenClaims(accessToken);
const { missing, isExpired, expiresIn } = analyzePermissions(claims, ["Notes.ReadWrite"]);
if (missing.length > 0) console.error(`Missing scopes: ${missing.join(", ")}`);
if (isExpired) console.error(`Token expired: ${expiresIn}`);

"Which request failed in a batch?" — Filter diagnostic log:

const failures = getDiagnosticLog().filter((e) => e.status >= 400);
failures.forEach((f) => console.error(`[${f.requestId}] ${f.method} ${f.url} -> ${f.status}`));

Output

• src/debug/diagnostic-middleware.ts — automatic Graph API call interception
• src/debug/token-inspector.ts — JWT decode and permission analysis (zero dependencies)
• debug/diagnostic_capture.py — Python diagnostic context manager with bundle export
• Diagnostic bundle JSON file with request-id, token claims, and error details
• Microsoft support ticket template with required fields

Error Handling

Debug Issue	Cause	Fix
request-id is null	Response headers not captured	Use diagnostic middleware; direct fetch bypasses header capture
JWT decode fails	Token is opaque (v1)	Graph tokens should be v2 JWT; check aud matches https://graph.microsoft.com
scp claim empty	App-only token (no delegated scopes)	App-only auth deprecated March 2025; switch to delegated
x-ms-ags-diagnostic missing	Not all errors include it	Optional header; rely on request-id for support tickets
Wrong tenant in claims	Multi-tenant app resolving wrong	Verify AZURE_TENANT_ID; check tid claim

Examples

// Generate diagnostic bundle after a failure
import { getDiagnosticLog } from "./debug/diagnostic-middleware";
import { decodeTokenClaims, analyzePermissions } from "./debug/token-inspector";
import { writeFileSync } from "fs";

const bundle = {
  bundle_version: "1.0", timestamp: new Date().toISOString(),
  log: getDiagnosticLog(),
  token: analyzePermissions(decodeTokenClaims(token), ["Notes.Read", "Notes.ReadWrite"]),
};
writeFileSync(`onenote-debug-${Date.now()}.json`, JSON.stringify(bundle, null, 2));

# Quick scope check from CLI
node -e "
  const t = process.env.GRAPH_TOKEN;
  const p = JSON.parse(Buffer.from(t.split('.')[1].replace(/-/g,'+').replace(/_/g,'/'), 'base64'));
  console.log('Scopes:', p.scp, '| Expires:', new Date(p.exp*1000).toISOString());
"
