I am encountering an issue while developing a todos app in MEAN stack with MongoDB installed locally. The error I am facing is related to the PUT request. Any assistance on resolving this problem would be greatly appreciated.
Error: Argument passed in must be a single String of 12 bytes or a string of 24 hex characters
