Facing a new error today while running Shopify app locally
“Does anyone know how much time Shopify will take to fix this issue?”![]()
New Liquid error encountered during local development: “Unknown tag ‘schema’” when using theme app extension blocks. This blocks running a Shopify app locally. Liquid is Shopify’s templating language; the ‘schema’ tag defines settings/metadata for theme app extension blocks.
Status: No fixes, workarounds, or official responses are provided in the thread yet. The discussion is open with the key question—Shopify’s timeline for a fix—unanswered.
