processDefinitionKey Filter by the key of the process definition the instances run on.
processDefinitionKeyIn Filter by a comma-separated list of process definition keys. A process instance must have one of the given process definition keys.

You need to supply multiple values separated by comma. If you want to use single value, use the filter processDefinitionKey
