I'm currently building a flow to create an event when a new email arrives. I have used the html to text and compose actions to pull the data I need for the event start & end date/times, however the format in the compose action appears as per attached image
I'm now trying to write the expression in the create event action that converts the compose actions to correct format in the start time and end time parameters so that the event can be created. All expressions I have tried are returning an error message Unable to process template language expressions in action 'Create_event_(V4)' inputs at line '0' and column '0': 'In function 'formatDateTime', the value provided for date time string '21.02.2025 00:00:00' was not valid. The datetime string must match ISO 8601 format.'.
