Post-upgrade, my local UI5 app refused to start – here’s what happened?
After our backend was upgraded to SAP S/4HANA, I ran into an issue while starting a SAPUI5 app locally:
npm run start-local
Resulting in: “Command run failed with error spawn EINVAL”
Screenshot 1.1: Error Message
Note: EINVAL means “Invalid Argument”, usually caused by outdated tooling or environment mismatches.
How I Fixed It
Everything in my project looked correct, but the error persisted. I first verified the Node.js and npm versions to rule out environment or version mismatches.
npm -versionnode -v
However, the issue still remained. Eventually, I discovered that the real cause was an outdated UI5 Tooling version, which was no longer fully compatible after the backend upgrade.
Screenshot 1.2: Version Checks
Updating the UI5 Tooling solved the issue in my case:
npm install -g @ui5/cli
Screenshot 1 .3: Tooling upgrade
then tried to re-run locally:
npm run start-local
After this, the app started successfully running (no more EINVAL errors)
Points to be remembered:
Keep UI5 Tooling as well as node.js up to date, especially after backend upgrades like S/4HANA.When you see spawn EINVAL, check your tooling version first, it’s often the simplest fix.Align your local environment with backend changes to avoid unexpected errors.
Updating the tooling was a small step that saved a lot of debugging time and made the app fully compatible with the new backend.
