Getting Error - "Cannot read properties of undefined (reading 'replace')" on Flow

[ronspar]

Hello, I am working on a Flow where we need to determine if an end_date is >90 days after a start_date. Below is a screenshot of an error that I receive when trying to use the function button to add 90 days to the start date and determine is end_date is after start_date(+90 days). Any suggestions on why this doesn't work?
