Additional context

Initially it was running fine but after about 24 hours when I wen back to the explorer I see this issue. I suspect that it's not able to calculate the halving for the local network as the block speed etc. isn't uniform and much quicker than normal bitcoin chain (10seonds). A quick fix would be to disable the halving calc when running local testnets, not sure if that's already available to configure in the env.

It's just the home page that's crashing other pages like block view etc. is still working fine
