## What it does

This GitHub Copilot rule applies across the project with `applyTo: '**'`. It explains the fields exposed by `DataverseError`, such as its code, HTTP status, source, and transient flag, and shows how to convert an exception into a dictionary for logging.

The examples cover authentication, permission, missing-resource, and validation failures. For transient faults and rate limits, the guide demonstrates retries with exponential backoff; it advises against retrying 401, 403, and 400 responses. The SDK has minimal built-in retry support, so rate-limit handling needs attention in your own code.

It also distinguishes `DataverseError` handling from `AzureError` handling. Since the rule targets `**`, its guidance applies to every project file, not just Dataverse calls.

## Requirements
- Works with: Azure

## Install

### GitHub Copilot (native platform)

**Manually: put the files in place**
- File: `.github/instructions/dataverse-python-error-handling.instructions.md` — The applyTo field sets which files it applies to

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/dataverse-python-error-handling.md` — The paths frontmatter field limits the files: move applyTo from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### Cursor

**Manually: put the files in place**
- File: `.cursor/rules/dataverse-python-error-handling.mdc` — Frontmatter: description, globs, alwaysApply. Move applyTo from the source into globs, or the rule will not attach on its own

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/dataverse-python-error-handling.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/dataverse-python-error-handling.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/instructions/dataverse-python-error-handling.instructions.md

## When to use it
- inspect Dataverse failures by HTTP status
- separate transient faults from permission errors
- retry requests with exponential backoff
- record exception details for debugging

## Example prompts
- Review this Dataverse call and suggest retry handling for a 429 response.
- Check whether this request should be retried after a 401 or 503.
- Add handling for `DataverseError` and `AzureError` around this Dataverse call.

# Dataverse SDK for Python — Error Handling & Troubleshooting Guide

Based on official Microsoft documentation for Azure SDK error handling patterns and Dataverse SDK specifics.

## 1. DataverseError Class Overview

The Dataverse SDK for Python provides a structured exception hierarchy for robust error handling.

### DataverseError Constructor

```python
from PowerPlatform.Dataverse.core.errors import DataverseError

DataverseError(
    message: str,                          # Human-readable error message
    code: str,                             # Error category (e.g., "validation_error", "http_error")
    subcode: str | None = None,            # Optional specific error identifier
    status_code: int | None = None,        # HTTP status code (if applicable)
    details: Dict[str, Any] | None = None, # Additional diagnostic information
    source: str | None = None,             # Error source: "client" or "server"
    is_transient: bool = False             # Whether error may succeed on retry
)
```

### Key Properties

```python
try:
    client.get("account", record_id="invalid-id")
except DataverseError as e:
    print(f"Message: {e.message}")           # Human-readable message
    print(f"Code: {e.code}")                 # Error category
    print(f"Subcode: {e.subcode}")           # Specific error type
    print(f"Status Code: {e.status_code}")   # HTTP status (401, 403, 429, etc.)
    print(f"Source: {e.source}")             # "client" or "server"
    print(f"Is Transient: {e.is_transient}") # Can retry?
    print(f"Details: {e.details}")           # Additional context
    
    # Convert to dictionary for logging
    error_dict = e.to_dict()
```

## 2. Common Error Scenarios

### Authentication Errors (401)

**Cause**: Invalid credentials, expired tokens, or misconfigured settings.

```python
from PowerPlatform.Dataverse.client import DataverseClient
from PowerPlatform.Dataverse.core.errors import DataverseError
from azure.identity import InteractiveBrowserCredential

try:
    # Bad credentials or expired token
    credential = InteractiveBrowserCredential()
    client = DataverseClient(
        base_url="https://invalid-org.crm.dynamics.com",
        credential=credential
    )
    records = client.get("account")
except DataverseError as e:
    if e.status_code == 401:
        print("Authentication failed. Check credentials and token expiration.")
        print(f"Details: {e.message}")
        # Don't retry - fix credentials first
    else:
        raise
```

### Authorization Errors (403)

**Cause**: User lacks permissions for the requested operation.

```python
try:
    # User doesn't have permission to read contacts
    records = client.get("contact")
except DataverseError as e:
    if e.status_code == 403:
        print("Access denied. User lacks required permissions.")
        print(f"Request ID for support: {e.details.get('request_id')}")
        # Escalate to administrator
    else:
        raise
```

### Resource Not Found (404)

**Cause**: Record, table, or resource doesn't exist.

```python
try:
    # Record doesn't exist
    record = client.get("account", record_id="00000000-0000-0000-0000-000000000000")
except DataverseError as e:
    if e.status_code == 404:
        print("Resource not found. Using default data.")
        record = {"name": "Unknown", "id": None}
    else:
        raise
```

### Rate Limiting (429)

**Cause**: Too many requests exceeding service protection limits.

**Note**: The SDK has minimal built-in retry support. Handle transient consistency issues manually.

```python
import time

def create_with_retry(client, table_name, payload, max_retries=3):
````
