Description
In the
collectFieldsfunction, whenFirstBlockNumberis 0, calculatingLastFinalizedBlockNumber = uint(FirstBlockNumber) - 1would cause an integer underflow, resulting in a very large unsigned integer value.Changes
Added validation for
FirstBlockNumberto ensure it's not 0, preventing underflow when calculatingLastFinalizedBlockNumber.Checklist
