When working with JSON data, you may encounter issues such as trailing commas, mismatched braces, or incorrect data types that make the JSON invalid. {% data variables.product.prodname_copilot_chat %} can help you debug and fix these errors by suggesting corrections to fix invalid JSON.
|
|
|
|
## Example scenario
|
|
|
|
Consider a scenario where an application consumes JSON data from an API, but the response fails to parse due to invalid formatting. You receive the error message:
|
|
|
|
```bash
|
|
Error: Parse error
|
|
----------------------^
|
|
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'
|
|
```
|
|
|
|
Below is the JSON data that caused the error:
|
|
|
|
```json
|
|
{
|
|
"location": "San Francisco",
|
|
"current_weather": {
|
|
"temperature": 18,
|
|
"unit": "Celsius",
|
|
"conditions": "Cloudy
|
|
},
|
|
"forecast": {
|
|
"day": "Monday",
|
|
"high": 22,
|
|
"low": 15,
|
|
"precipitation": 10
|
|
}
|
|
}
|
|
```
|
|
|
|
## Example prompt
|
|
|
|
`Why is my JSON object invalid and how can I fix it?`
|
|
|
|
## Example response
|
|
|
|
{% data reusables.copilot.example-prompts.response-is-an-example %}
|
|
|
|
{% data variables.product.prodname_copilot_short %} might suggest that your JSON is invalid because it's missing a closing quote for the `conditions` value. Here is the corrected JSON:
|
|
|
|
```json
|
|
{
|
|
"location": "San Francisco",
|
|
"current_weather": {
|
|
"temperature": 18,
|
|
"unit": "Celsius",
|
|
"conditions": "Cloudy"
|
|
},
|
|
"forecast": {
|
|
"day": "Monday",
|
|
"high": 22,
|
|
"low": 15,
|
|
"precipitation": 10
|
|
}
|
|
}
|
|
```
|
|
|
|
In this example response, {% data variables.product.prodname_copilot_short %}'s suggestions include fixing the closing quote for the `conditions` value, which resolves the JSON parsing error.
