There are thousands of them in our log, try to restart service everything went back to normal.

 ERROR: Multicall error: Error: Multicall received an empty response. Check your call configuration for errors.

Look like, cross-fetch didn't working well in Node.js:

https://github.com/makerdao/multicall.js/blob/master/src/helpers.js#L122-L127

Could you guys update cross-fetch to 3.0.6.

Our service reach this state because of the call's payload is too big.
