Wrangler >=4.44 defaults per-version Preview URLs to match the workers_dev setting when preview_urls isn't set explicitly. This worker has workers_dev: false, so every deploy (each branch build runs 'wrangler versions upload') reset Preview URLs back to disabled, requiring a manual dashboard re-enable that the next build undid. Set preview_urls: true so PR/branch preview URLs persist across deploys. Enables preview URLs only — the production workers.dev route stays off.

Problem
Cloudflare Preview URLs for branch/PR builds keep silently turning off — you re-enable the toggle in the dashboard, then the next branch build disables it again.
Root cause (confirmed via Cloudflare docs)
Wrangler ≥ 4.44 defaults per-version Preview URLs to match the
workers_devsetting whenpreview_urlsisn't set explicitly. This worker has"workers_dev": false, and every deploy (each branch build runswrangler versions upload) reapplies the config → Preview URLs reset to disabled. With many branch builds, the dashboard toggle gets undone constantly.Fix
Set
"preview_urls": trueinwrangler.jsoncso previews persist across deploys. This enables preview URLs only — the productionworkers.devroute staysfalse.Unblocks clicking the per-version / branch preview URLs (e.g. for verifying PR builds like the sitemap work in #222).
Note
Low Risk
Single deploy-config flag with no application code changes; only affects Cloudflare preview URL behavior, not production routing.
Overview
Sets
preview_urls: true inwrangler.jsoncso branch/PR deploys stop turning off Cloudflare per-version Preview URLs on everywranglerupload.With Wrangler ≥ 4.44, missing
preview_urlsdefaults it to matchworkers_dev(falsehere), which overwrote manual dashboard toggles.workers_devstaysfalsefor production; only preview URLs are explicitly enabled.Reviewed by Cursor Bugbot for commit 9fd4012. Bugbot is set up for automated code reviews on this repo. Configure here.
