Same issues here! we’ve problem pushing updates on the code, without any changes on package or github actions. for us it’s a major issue, we’ve to deploy in prod new changes! 
Topic summary
After upgrading to Remix v2.2.0, Oxygen deployments triggered via GitHub Actions began failing with “Unable to verify worker deployment completion.” Others reported identical failures even without upgrading; clearing the Actions cache did not help.
Initial response from Shopify indicated a platform-side issue was resolved, but users continued to see failures. One user suggested a workaround by adding a package.json resolution: “run/minimatch”: “8.0.0”, which helped them but not others.
Shopify later clarified the generic error stemmed from poor error reporting: user script errors were being masked as the blanket message. They rolled out an admin update to surface the actual errors and are improving CLI error surfacing.
Post-update, some still saw “Process completed with exit code 1” in Actions, but were advised to check the Admin > Hydrogen channel for detailed errors. The original poster confirmed a useful error appeared there and they could proceed.
Status: Partially resolved. Admin now shows actionable error messages; underlying failures may be project-specific. Further troubleshooting continues via direct support. (Oxygen: hosting for Hydrogen storefronts; Workers likely deployed to Cloudflare.)
Screenshots were shared but not essential to the resolution.
