Question on Etherscan and Geth/Erigon

if anyone can help me please: https://etherscan.io/tx/0x89a1ed3d7e57c752a3b195ed4b584f7ac2c68e6ad532907596d7f108a90847ad/advanced

internal transactions tab lists all the transactions with the gas Limit

call_6 has a limit of 30,046 but erigon and geth debug_traceTransaction doesnt return a gas or gas used fields

how is this number calculated?

erigon output ,{"type":"CALL","from":"0x7a250d5630b4cf539739df2c5dacb4c659f2488d","to":"0xf43c68d57f92adfaf2173422d487259a789d9b2f","value":"0x148e25f9594227c","input":"0x","output":"0x"}]}
