Geeting error UNPREDICTABLE_GAS_LIMIT

[valeriagrazzini]

Hi Pedro, when it comes to run the application and the profitable value is true
I get the ERROR:

reason: 'cannot estimate gas; transaction may fail or may require manual gas limit',
code: 'UNPREDICTABLE_GAS_LIMIT',

Could you please help me out?

Same problem here, I just set gasLimit to something fixed like 5000000 and skip over it. Getting gasPrice from wallet works fine. I think in the end, the gasLimit doesn't matter very much, I think front-running bots will try and pre-empt your transaction with higher gasPrice i.e. higher GWEI.
