Filesystem Permission Error - Checkout UI Extension Development
Hi, I'm trying to build a Thank You page extension for my app following the Shopify docs. The AI assistant has tried to fix a persistent filesystem error without success. I'm not a developer, so I'm still learning about the platform and Shopify’s requirements, so I asked the AI to summarize the problem. ISSUE SUMMARY:
EACCES: permission denied, mkdir '/gadget/app/extensions/my-extension/dist'
Shopify CLI fails to create the dist/ build folder for Checkout UI Extension (purchase.thank-you.block.render) when running yarn shopify:dev in Gadget cloud environment.

ENVIRONMENT:
Platform: Gadget Cloud Development Environment
Extension Type: checkout_ui_extension
Target: purchase.thank-you.block.render
Command: yarn shopify:dev (Shopify CLI in Gadget terminal)
\ud83d\udcdd EXTENSION CONFIGURATION:
toml
api_version = "2024-10"
name = "my-checkout-extension"
handle = "my-checkout-extension"
type = "checkout_ui_extension"
output_dir = "/tmp/my-extension-dist" # Attempted fix
[[targeting]]
target = "purchase.thank-you.block.render"
[capabilities]
network_access = true
api_access = true
\ud83d\udd0d BEHAVIOR COMPARISON:
Theme Extension: Compiles successfully, no filesystem issues
Checkout UI Extension: Cannot create dist/ folder
\ud83d\udd27 ATTEMPTED SOLUTIONS (ALL FAILED):
Manual directory creation:
bash
mkdir dist
bash
mkdir -p /tmp/my-extension-dist
ln -sfn /tmp/my-extension-dist dist
toml
output_dir = "/tmp/my-extension-dist"
Result: Shopify CLI ignores this setting and still attempts to create local dist/ folder
EACCES: permission denied, mkdir '/gadget/app/extensions/my-extension/dist'
