HubSpot API call fail INVALID_DATE not midnight!
When making a HubSpot API call to update a date picker field, I’m getting a response with “response code 400”, “error INVALID_DATE”, and the message includes “not midnight!”. This is why I’m getting this error and how I fixed this call.
PHP Convert to DateTimeImmutable
In PHP 5.5 the DateTimeImmutable class was introduced. Immutable objects are nice in that they can not be modified, which helps reduce the likelihood I make certain types of errors. This is how to ensure the DateTime you’re working with is immutable.
