Error when submitting form via V3 api

Hello everyone
i’m having trouble with a form submission via API.

this is the error message that I’m getting
{‘status’: ‘error’, ‘message’: ‘Invalid input JSON on line 1, column 634: Cannot build FormSubmissionValue, some of required attributes are not set [value]’, ‘correlationId’: ‘2b91dc22-9a5f-4fbb-bec5-96e51ba0c2d5’}
I cant’t spot the error in the JSON, that I paste below.
