found no matching assets for expr: %q

Error message

found no matching assets for expr: %q

What it means

AssetStore.FindMatch ran the regexp over every registered asset and got zero hits — the requested asset was never added to the store (wrong key in the spec, or the file is missing from the kops binary/image assets).

Solutions

1. Check the asset expression/key against the files actually bundled with your kops build
2. Rebuild or reinstall kOps so the expected asset files are embedded
3. Fix the referencing spec field so it names an asset that exists
