# Miro Common Errors

## Overview

Quick reference for Miro REST API v2 errors organized by HTTP status code, with real error response bodies and proven fixes.

## Prerequisites

- Access token configured
- `curl` available for diagnostic requests

## Quick Diagnostic

```bash
# 1. Verify API connectivity
curl -s -o /dev/null -w "%{http_code}" https://api.miro.com/v2/boards \
  -H "Authorization: Bearer $MIRO_ACCESS_TOKEN"

# 2. Check token validity
curl -s https://api.miro.com/v1/oauth-token \
  -H "Authorization: Bearer $MIRO_ACCESS_TOKEN" | jq

# 3. Check Miro status page
curl -s https://status.miro.com/api/v2/status.json | jq '.status.description'
```

## Error Reference

### 400 — Bad Request

```json
{
  "status": 400,
  "code": "invalidInput",
  "message": "Could not resolve the value for parameter: data.content",
  "context": { "fields": [{ "field": "data.content", "message": "Required" }] }
}
```

**Common causes:**
- Missing required fields in request body
- Wrong data types (string instead of number for position)
- Invalid enum values (e.g., `shape: 'oval'` — correct is `shape: 'circle'`)

**Fix:** Cross-reference your request body with the [REST API reference](https://developers.miro.com/docs/rest-api-reference-guide). Each item type has specific required fields.

**Sticky note required fields:** `data.content`, `data.shape` (`square` or `rectangle`)
**Shape required fields:** `data.shape` (see `miro-sdk-patterns` for valid shapes)
**Connector required fields:** `startItem.id`, `endItem.id`

---

### 401 — Unauthorized

```json
{
  "status": 401,
  "code": "tokenNotProvided",
  "message": "Access token is not provided"
}
```

```json
{
  "status": 401,
  "code": "tokenExpired",
  "message": "Access token has expired"
}
```

**Common causes:**
- Missing `Authorization: Bearer <token>` header
- Access token expired (tokens last 3599 seconds / ~1 hour)
- Using client_id/client_secret instead of access_token

**Fix:**
```bash
# Check if token is set
echo "Token length: ${#MIRO_ACCESS_TOKEN}"

# Refresh expired token
curl -X POST https://api.miro.com/v1/oauth/token \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=refresh_token" \
  -d "client_id=$MIRO_CLIENT_ID" \
  -d "client_secret=$MIRO_CLIENT_SECRET" \
  -d "refresh_token=$MIRO_REFRESH_TOKEN"
```

### 403 — Forbidden

```json
{
  "status": 403,
  "code": "insufficientPermissions",
  "message": "Required scopes: boards:write",
  "context": { "requiredScopes": ["boards:write"] }
}
```

**Common causes:**
- Token lacks required OAuth scope
- User does not have board-level permission (viewer trying to write)
- Team-level restrictions prevent the operation

**Fix:**
1. Check which scopes your token has vs. what the endpoint requires
2. Update scopes in your Miro app settings at https://developers.miro.com
3. Re-authorize the user to get a token with updated scopes

| Endpoint Category | Required Scope |
|-------------------|---------------|
| GET boards/items | `boards:read` |
| POST/PATCH/DELETE boards/items | `boards:write` |
| GET team/members | `team:read` |
| Organization endpoints | `organizations:read` |

---

### 404 — Not Found

```json
{
  "status": 404,
  "code": "boardNotFound",
  "message": "Board not found or access denied"
}
```

**Common causes:**
- Board ID is wrong or has been deleted
- Item ID references a deleted item
- Token owner does not have access to the board

**Fix:**
```bash
# Verify board exists and you have access
curl -s https://api.miro.com/v2/boards/$BOARD_ID \
  -H "Authorization: Bearer $MIRO_ACCESS_TOKEN" | jq '.id, .name'

# List boards to find correct ID
curl -s "https://api.miro.com/v2/boards?limit=10" \
  -H "Authorization: Bearer $MIRO_ACCESS_TOKEN" | jq '.data[] | {id, name}'
```

---

### 409 — Conflict

```json
{
  "status": 409,
  "code": "duplicateTagTitle",
  "message": "A tag with this title already exists"
}
```

**Common causes:**
- Creating a tag with a title that already exists on the board
- Concurrent modifications to the same item

**Fix:** Fetch existing tags first and reuse their IDs instead of creating duplicates.

---

### 429 — Rate Limited

```json
{
  "status": 429,
  "code": "rateLimitExceeded",
  "message": "Rate limit exceeded"
}
```

**Response headers:**
```
X-RateLimit-Limit: 100000
X-RateLimit-Remaining: 0
X-RateLimit-Reset: 1700000060
Retry-After: 30
```

**Fix:** Honor the `Retry-After` header. See `miro-rate-limits` for complete backoff patterns. The global limit is 100,000 credits/minute.

---

### 500 / 502 / 503 — Server Error

**Common causes:**
- Miro platform issue (check https://status.miro.com)
- Transient infrastructure error

**Fix:**
1. Check Miro status page
2. Retry with exponential backoff (see `miro-rate-limits`)
3. If persistent (>5 min), it is a Miro-side issue — enable fallback mode

## Programmatic Error Handler

```typescript
async function handleMiroError(response: Response, context: string): Promise<never> {
  const body = await response.json().catch(() => ({}));

switch (response.status) {
    case 401:
      console.error(`[Miro:${context}] Token expired/invalid. Refreshing...`);
      // Trigger token refresh
      break;
    case 403:
      console.error(`[Miro:${context}] Missing scopes: ${body.context?.requiredScopes?.join(', ')}`);
      break;
    case 429:
      const retryAfter = response.headers.get('Retry-After') ?? '60';
      console.warn(`[Miro:${context}] Rate limited. Retry after ${retryAfter}s`);
      break;
    default:
      console.error(`[Miro:${context}] ${response.status}: ${body.message ?? 'Unknown error'}`);
  }

throw new Error(`Miro API ${response.status}: ${body.message ?? context}`);
}
```

## Escalation Path

1. Run diagnostics above
2. Collect evidence with `miro-debug-bundle`
3. Check https://status.miro.com
4. File support ticket with request ID (from `X-Request-Id` response header)
