Graph for multi chain assets is missing historical data

[yabirgb]

Problem Definition

I have wstEth in optimism, ethereum and arbitrum but the graph for the asset only contains the last balance that is a virtual point added by the frontend. As it can bee seen in the console the response from the backend is empty.

Clicking in one of the chains shows correctly the graph of balance

I have USDC across 2 chains in production (1.30.2) and I don't see any problems. MATIC in 2 chains also fine. DAI in 4 chains. Works fine.

@yabirgb I don't think this is a generic bug. I think you will have to debug this yourself.
