OK I am validating before I create any. Perhaps it was because there was a problem with the sandbox I created this thread but it’s resolved now.
I get an warning using the php client:
vendor/stuartapp/stuart-client-php/src/Stuart/Converters/JsonToJob.php on line 34
PHP Deprecated: DateTime::createFromFormat(): Passing null to parameter #2 ($datetime) of type string is deprecated
In this case is passing a time always necessary?
