Was this something which used to work for you, and then stopped?

It used to work, and then stopped

For two of our repos, Renovate has been generating PRs with only changes to package.json. To fix this we've had to manually run npm i on the branch to get the changes into package-lock.json.

I've tried utilizing postUpdateTasks in our Renovate config and configured it to run npm i when changes to package.json are detected.

"postUpgradeTasks": {
   "commands": ["npm i"],
   "fileFilters": ["package.json"]
 }

1. Renovate updates the version in package.json
2. The postUpgradeTasks runs npm i
3. npm sees the updated version in package.json but isn't fetching the new package. We are only seeing that the old package version is removed from package-lock.json

Before we start working on your issue we need to know exactly what's causing the current behavior. A minimal reproduction helps us with this. Discussions without reproductions are less likely to be converted to Issues.

Please follow these steps:

1. Read our guide on creating a minimal reproduction.
2. Go to our minimal reproduction template repository.
3. Select the Use this template button to create a new repository based on the template.
4. Work on the minimal reproduction in your own repository.
5. Fill out the information in your repository's README.md.
6. Add the link to your reproduction to the first post of your Discussion. If you are not the original author, you can post a new comment with the link.
