How to solve estimateGas failed on Tomochain?

I bulk address array to smart contract this smart contract is transfer erc20 multiple times, but i don’t fix gas on transaction i use estimateGas and auto gas on ethers library is work sometime but not always

i guess blocktime on tomochain is instants time(2sec) is estimateGas fail because some block is close before calculate gas

how to solve or can manual fix gas from bytes code ?

You should fix gas for your tx at this time.
For estimateGas, we will investigate it if we have more information or logs.
