@saurabhraghuvanshii, we're going to have repeat of our last interaction, I fear. The PR you've opened shouldn't be merged unless its an emergency. What needs to be done is to identify the root cause of why the automated dependency updates failed, fix that, and then make sure that the upgrade is completed.

[saurabhraghuvanshii]

@sistent/sistent declares @meshery/schemas as a peer dependency (in its package.json). Peer dependencies are not installed automatically by the package; the host application is expected to list and install them. The layer5 site did not have @meshery/schemas as a dependency, so the bundler could not resolve it when building code that uses sistent.
