Hi I’ve submit and adapt our datasource plugin for Grafana 13 and encountered an issue during plugin submission, the submission failed with the following error:
Could not process plugin archive: plugin.json invalid: data must NOT have additional properties
After checking the plugin archive, the additional property appears to be:
“mixed”: true
Our datasource plugin relies on this capability to work properly with mixed queries / mixed datasource scenarios. The plugin works as expected in Grafana locally, but the submission validator rejects the `mixed` field in `plugin.json`.
Could you please help confirm:
1. Is the `mixed` property still officially supported for datasource plugins in Grafana 13?
2. If yes, could the plugin submission validator / plugin.json schema be updated to allow this property?
3. If `mixed` is no longer the recommended approach, what is the official replacement or migration path for datasource plugins that need to support mixed query behavior?
We can provide the plugin archive, plugin.json, and validation logs if needed. plugin id: leoswing-comparequeries-datasource
Could anyone help to ignore the error tips and approve the plugin submission?
