if it occurs when using estimateGas, you have to reduce claim times; or if you set gas manually, you have to reduce gas (mybe claim times as well).

when you call Call function in air_drop_multi_claim_with_selfdestruct contract, the contract will create several Claimer subcontract, which will claim airdrop, transfer to your account and selfdestruct.
