When I tried to swap from USDC to USDC, the above error appeared.

I think this is the same thing that pkr mentioned in the developer-support channel on discord. Please check it.

Is it resolved please?

It seems to happen when pass through a Pool with a TVL of 0, which causes an error in the calculation of the jsbi library.

Not sure if this has been fixed in the current version of @jup-ag/core, but at the time I modified jsbi so that the division by zero error does not occur.
