# Logs
A great debugging resource is the ability to view your function logs. To do so, go to the left sidebar and select the **Logs** icon, as shown below, to view your function's execution history:
In the function logs, you can confirm that data was successfully posted to Ubidots with the **201** response code:
This is what your function returns. It must be in JSON dictionary format. In your code, make sure to use **return** to exit the function and return the dictionary.
{% tabs %}
{% tab title="NodeJS" %}
```javascript
return response.data;
```
{% endtab %}
{% tab title="Python" %}
```python
return {"status": "Ok", "result": req.json()}
```
{% endtab %}
{% endtabs %}
You can also use logs for debugging. Print any variables defined earlier, or print any message that needs to be displayed to the user.
{% tabs %}
{% tab title="NodeJS" %}
```javascript
console.log("[INFO] Request result:");
console.log(response);
```
{% endtab %}
{% tab title="Python" %}
```python
print("[INFO] Request result:")
print(req.text)
```
{% endtab %}
{% endtabs %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://dev.ubidots.com/ubifunctions/getting-started/logs.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
