ConfigEditor & QueryEditor mutates React props

[hugohaggmark]

We’ve noticed that this plugin mutates React props in Grafana. For example, this line mutates the jsonData prop passed into the React component and this line mutates the query prop passed into the React component.

While this currently works in Grafana, it may not be compatible with future versions and could lead to runtime errors. To ensure long-term stability, we recommend avoiding prop mutation. You can find more details in the React docs:
