Product page: Size Chart adding metafield Error

Store Design

Topic summary

Shopify product template showed dynamic source errors when adding a Size Chart via a product metafield, citing missing fields like product.metafields.custom.product_lookbook_images_* and blocking save/preview.

Setup: Size Chart/Guide pages with images were created and linked through a product metafield (type: Page), but the editor still errored. “Metafield” = custom data field; “Dynamic source” = a referenced data field used by the theme.

Guidance offered:

  • Option 1: Use a Theme Customizer pop-up section and bind the Page-type metafield to it.
  • Option 2: Create a dedicated size-guide metafield and render it via a custom section using Liquid (Shopify’s templating language) for per-product display.
  • Suggested reverting recent changes and verifying the metafield definition (type: Page). Screenshots confirmed definitions looked correct.

Diagnosis: Likely issue in the template code; requested a code review/debug as definitions appeared fine.

Outcome: Merchant later confirmed they identified and fixed the issue themselves (no specific fix shared). Status: resolved; no open questions or decisions pending.

Great! You have 70% work done already
So From what I have understood is you have meta field in which there is a page with image of size chart
One way is Use a pop-up section from customizer, it and link the metafield to it like in picture

Or second method would be creating a metafield with just the size guide and displaying this on product page with a custom section using liquid programming language this way it would be dynamic for every product

and regarding the error, change everything back as it was, we’ll get this done from the customizer only!!!

I guess, the template code might need a review or Code has to be debugged, this definitions has no problems.
I will have to go through the store and then I’ll be able to address
