working on this

@Haarolean there is something wrong with PNPM build. When I try to build the project it fails. Also it's failing your github actions E2E PR smoke tests for most of the PRs. As a workaround I commented out the frontend-maven-plugin plugin from contract/pom.xml

Failed to execute goal com.github.eirslett:frontend-maven-plugin:1.15.1:pnpm (pnpm build) on project api: Failed to run task: 'pnpm build' failed. org.apache.commons.exec.ExecuteException: Process exited with an error: 2 (Exit value: 2) -> [Help 1]

1. your build is failing perhaps due to missing npm or something. You can build with local profile instead locally.
2. We're aware of the flaky e2e test
