}

```
and .npmrc

```
engine-strict=true

```

```

Any hints or remarks?

If we remove `engine-strict` it works, but we are working in a big monorepo with a lot of developers.

Best regards

### What you expected to see, versus what you actually saw

Dependabot creates PR with dependency updates without any error and the used tooling versions.

Reproduce the failure using the package.json, .npmrc, and dependabot.yml examples, with pnpm 10.4.1 and Node 22.14.0. Start by tracing npm ecosystem handling of engine-strict and the reported Node version, then verify that a dependency update completes with the configured tooling versions.
