# Error Handling

## Error Handling

Error responses will include informative messages to help troubleshoot issues:

### Method Errors

```
If you use an incorrect HTTP method:
```

```json
{"error": "Method Not Allowed POST: /webapi/apps"}
```

### Missing Input Errors

If required inputs are missing (e.g., when running an LLM App):

```json
{"errors": "internal error. Expecting value: line 1 column 1 (char 0)"}
```
