Liquid error: Could not find asset snippets/__default-template.liquid- Error on live site

Store Design
, , , ,

Topic summary

Liquid error occurs when the theme tries to include a missing snippet (__default-template.liquid) after migrating from Webflow to Shopify via Udesly and adding third‑party apps (e.g., product customizers, subscriptions).

Key points and fixes:

  • Root cause: Shopify Liquid (templating language) is referencing a snippet that doesn’t exist in Snippets.
  • Fix option A: Remove references to “__default-template” in theme.liquid (Online Store > Themes > Edit code). This cleared the error but left a blank page where the app UI should load, because the snippet’s logic is missing.
  • Fix option B: Create Snippets/__default-template.liquid. This suppresses the error but still shows a blank page unless the app injects the required code. App support should reinstall or provide the snippet’s contents.
  • Other causes noted: Google reCAPTCHA “/challenge” page triggered on contact form submissions; device/IP-specific behavior despite settings.
  • Structural issue from Udesly/Webflow: Missing required pages in Webflow (e.g., Blog, Our Story) caused errors. Creating those pages and applying Udesly custom attributes to link elements to Shopify editors resolved it for one user.

Status: Partially resolved with workarounds; app-specific fixes and guidance on “linking elements” and subscription apps (e.g., Appstle) remain open.

Hi, I recently created a website on Webflow and I needed to install a product customizer/preview for a print on-demand store. I decided to use a shopify app for the functionality so I used Udesly to transfer from Webflow to Shopify but after I added the apps (I’ve tried this with 3 product customizer apps) it gave me this error:

“Liquid error: Could not find asset snippets/__default-template.liquid”

Does anyone know how I could fix this? *I don’t know how to code *

Hi @Bdesign

This is Victor from PageFly - Shopify Page Builder App

This error is showing because your store is trying to access an undefined file.
And this is very easy to fix, please follow my instructions below :

Step 1: Online Stores > Themes > More Actions > Edit code

Step 2: click on theme.liquid and open search tool by hit Ctrl + F or CMD + F ( if you using MAC )
then in the search box, please find for : “__default-template”
After you found that line of code, please feel free to remove it.

Very simple

Hope this can help you solve the issue

Best regards,

Victor | PageFly

Hi @Bdesign

The error message occurs because a code tries to find the ‘__default-template.liquid’ file in Snippets folder.

You can add a __default-template.liquid file.
Go to Online Store → Themes → Edit code. https://prnt.sc/8WaQmdSW_Hk7
Add a ‘__default-template.liquid’ in Snippets folder https://prnt.sc/isWVs6EnUm04

But you should contact app team support to fix it.

Best regards,

Thank you! so this took away the error message but it now just opens up to a blank page whenever I click the button that is supposed to show the customizer

Thank you but I wasn’t able to find any “__default-template” but when i added one into the snippets, it took away the error but now I’m just left with a blank page

I think it shows a blank page because that file doesn’t have any logic or functionality inside that.
If that file come from any 3rd app i suggest you to contact them to re-install the code for you.

Hi, @Bdesign
Did you find a solution? Im having a similar issue.
I use Webflow → Udesly → Shopify integration

And in the url: /challenge#contact_form

The problem was with recaptcha and /challenge page. Works on my phone but my desktops ip goes to the captcha even tho i disabled it

@Bdesign & whoever is having the same issue!

I had the same issue, and by looking at other udesly approved themes in the designer mode I think I’ve figured it out.

The reason why this error seems to be happening is because, in my case, I had not created all the pages required for it IN WEBFLOW. For example, my blog was going to a 404 page, but I had a CMS collection, but I did not have a BLOG page. Same for Our Story, I have the page on Shopify, but not on Webflow.

Once I created the pages, it was working but you need to link the elements inside webflow, with the udesly custom attribute to the Shopify editors just like you might have already done with other elements so you can edit them.

Hope this helps! Please share your feedback and what you find or if there is anything I haven’t touched upon.

Cheers!

Hi @JackTr Can you expand on what you mean “Link the elements inside web flow”?

I am trying to use a subscription management app, and it creates a page. But I am unsure what this means to link elements. There is nothing to link.
