WalkthroughThis PR updates dependency management for the proxy-backend plugin by transitioning from workspace references to pinned versions for Backstage dependencies and upgrading Express. The changes lock @backstage/backend-common to version 0.24.1 and @backstage/config to version 0.1.1, moving away from workspace protocol references. Additionally, Express is upgraded from version 4.17.1 to 4.22.0, which likely includes important security patches and bug fixes. These modifications aim to improve dependency stability, ensure version consistency, and address potential security vulnerabilities in the Express framework. Changes

Code Review
This pull request from Snyk aims to fix two security vulnerabilities by updating dependencies. While the update to express seems correct, the changes to the @backstage/ dependencies are problematic. Specifically, @backstage/config is being downgraded to a very old version, which will almost certainly break the application. Additionally, @backstage/backend-common is being pinned to a specific version instead of using the workspace version, which is not ideal in a monorepo setup and can lead to maintenance issues and version conflicts. These changes, especially the downgrade, are likely the reason why yarn.lock could not be updated, as mentioned in the PR description. I've left specific comments on the problematic dependency changes.

This change downgrades @backstage/config from the workspace version (1.0.8) to 0.1.1. This is a major downgrade and is very likely to cause build failures or runtime errors due to API incompatibilities. Other packages like @backstage/backend-plugin-api still depend on the workspace version of @backstage/config, which will lead to type conflicts. This change seems incorrect and should be reverted. The PR description's warning about yarn.lock failing to update is probably caused by this invalid dependency resolution.

Pinning @backstage/backend-common to a specific version (0.24.1) instead of using the workspace version (workspace:^, which resolves to 0.19.2-next.0) can lead to issues. It may introduce multiple versions of the package and its dependencies, and can cause type incompatibilities with other packages that rely on the workspace version. While this might be a temporary fix for a vulnerability, the better long-term solution in a monorepo is to upgrade the version of @backstage/backend-common across the entire workspace.

plugins/proxy-backend/package.jsonNote for zero-installs users
If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the
.yarn/cache/directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to runyarnto update the contents of the./yarn/cachedirectory.If you are not using zero-install you can ignore this as your flow should likely be unchanged.
