Help with Flow for checking if Excel sheet is Blank



I am after some assistance if someone is able to help me please 🙂


Basically, I have a Power Automate Flow which runs daily as an 'End of Day' process for another process. I want this to stop the process if the table in the Excel spreadsheet is blank. 


I have a 'List Rows in Table' function called 'Acquire Values from WC School Uploader' to obtain the data from the file and a Condition after this with the expression; 





empty(outputs('Acquire Values from WC School Uploader')?['value'])






However this produces an error while trying to save the file; "Flow save failed with code 'InvalidTemplate' and message 'The template validation failed: 'The action(s) 'Acquire Values from the WC School Uploader' referenced by 'inputs' in action 'Checks_if_Uploader_is_Blank' are not defined in the template.'.'."
