Does anyone know how to fix this?

```

The report concerns deployment of the demo-springboot function, where PUT /services/demo-springboot-service/functions/demo-springboot returns 400 with “Bad data in request body.” Start by reproducing this deployment and inspecting the request body sent at that endpoint; done means the function deploys successfully or the invalid payload and required correction are documented.
