Cannot estimateGas whereas gasLimit exists

[iboxgithub]

Hi,
please see the screenshot below: I do a populateTransaction with a manual gasLimit (is there a better way to do this?) and then when I try to estimateGas I have this error so I am not sure what I did wrong here...do I have to also put gasLimit in the estimateGas overrides?

I found the solution, it's because my contract didn't have WETH on it: is there a way to debug this though? Like a Tenderly debugger for estimateGas?

Tenderly does have a gas profiler. Also you cannot estimate gas if your tx is reverting. If you want to debug the cause of revert, just send a tx with a manual gasLimit high enoguh and see the tx over tenderly. Or ideally you can use their simulate tx feature which allows to enter to address and data (as well as other parameters) and you can get simulation results that can help you debug :)

yes that's what I came up to also, thanks a lot for your help ;)
