Transferring the conversation with @derek-ho here:

this 404 is caused by the absent of dashboards observability, since i'm waiting on the api migration, Right now i'm temporarily hooked the api to the dashboards observability still. And once we change that this should be gone.

According to the above we can close this for now.
