Posted on by Problematic 19

HI All

Error message prompted out -  " In function 'formatDateTime', the value provided for date time string '44865' was not valid. The datetime string must match ISO 8601 format.'"

 

my designed flow as below (the data of 'Compose' is from the Microsoft Form and it is set for input as a date)

The flow failed to run as error message indicated that the datestring does not comply with ISO 8601.
