What action can help locate a logical error in a script?

Utilizing breakpoints in the code, debugging, and examining variable values is a highly effective approach for locating logical errors in a script. This method allows a developer to pause the execution of the program at designated points, enabling them to inspect the state of various variables and the flow of control at that moment. By stepping through the code line by line, developers can observe how data changes and ensure that logic is executing as expected. This direct interaction with the code execution provides insights that lead to resolving discrepancies and errors efficiently.

While other methods like checking request logs or printing values can offer clues, they lack the detailed, hands-on control of debugging that breakpoints provide, which is crucial for identifying and understanding complex logical issues within the script.
