Hi everyone,

I’ve been using HubSpot for a while now and recently encountered an issue while trying to import CRM object data in the frontend. Previously, I could fetch CRM object data like this:

**{{ % set crm\_data = crm\_objects(“cars”, 10, “hs\_object\_id, name, brand, model”) % }}**  
**{{ % set all\_crm\_cars = crm\_data.results % }}**

**\<script\>**  
**const allCars = {{ all\_crm\_cars|tojson }};**  
**\</script\>**

However, I’m currently facing the following error when attempting the same:

`java.lang.StackOverflowErrorOriginating Exception: StackOverflowError`

Has there been any recent changes in the HubSpot platform regarding the way CRM object data is imported to the frontend? I’m wondering if this error is related to some update or change that I may have missed.

Any advice or insights would be greatly appreciated!

Thanks in advance!

It should

**{% set crm\_data = crm\_objects(“cars”, 10, “hs\_object\_id, name, brand, model”) %}**

One bracket, not two.

okay, that was a typo from my side.  
I actually did it with one bracket like this:

**{% set crm\_data = crm\_objects(“cars”, 10, “hs\_object\_id, name, brand, model”) %}  
{% set all\_crm\_cars = crm\_data.results %}**  
Its still showing me the same error in js.

Hi @MUlHuq

The way you are using the limit is not correct. Here is the code that I am using and it is working fine for me. Change the custom object name to cars and add the properties as per your requirement.  
code block --

```lia-code-sample
{% set fruits = crm_objects("fruits", "limit=10", "fruit_name") %}
{% if fruits.results is iterable %}
<ul>
 {% for fruit in fruits.results %}
<li style="color:#000">{{ fruit.fruit_name }}</li>
 {% endfor %}
</ul>
{% else %}
<p>No data found or invalid custom object.</p>
{% endif %}

```

I hope this will help you out. Please mark it as **Solution Accepted and upvote** to help another Community member.

Thanks!

Thank you for the feedback. Yes, I changed the limit.  
But the main issue is, I need these values to manipulate in JS.  
Do you have any idea how to do that?

Hi @MUlHuq,  
As I mentioned in your other thread, I think there _could_ be an issue on the Hubspot end.  
Even using the demo code form the [documentation](https://developers.hubspot.com/docs/reference/cms/hubl/functions#crm_objects) is throwing up errors and can’t publish.

```lia-code-sample
{% set objects = crm_objects("contact", "firstname__not_null=&limit=3", "firstname,lastname") %}
{{ objects }}

```

Won’t publish. Same error.  
And going back to existing modules that use crm\_objects, I can’t publish and changes to previously functional modules.

Yes, that is the only reason we can come up with.  
Let’s hope they fix this thing asap.
