Hello Team, I have created a flow in power automate that that is expected to identify changes in a excel file and send an email notification. Here are the steps as shown in the screenshot:

When tested, the flow fails at step 'For Each' and error is shown as: "Unable to process template language expressions for action 'Condition_1' at line '0' and column '0': 'The template language function 'greater' expects two parameter of matching types. The function was invoked with values of type 'String' and 'Integer' that do not match.'."
