Hello,

using Camunda 7.14

I have a Json variable in a process:

But when I fetch the process, the variable does not contain the value:

 'variables': {'variables1': {'type': 'Json',
                              'value': {'array': False,
                                        'boolean': False,
                                        'dataFormatName': 'application/json',
                                        'nodeType': 'OBJECT',
                                        'null': False,
                                        'number': False,
                                        'object': True,
                                        'string': False,
                                        'value': False},
                              'value_info': {}}},

I would expect somewhere "my_value" : "test1". How do i get the actual variable?

Regards,
Markus
