Hi Experts…
I can confirm that even if you create the parameters as JSON, the payload works. But unfortunately an error message always appears as a popup. From the perspective of Grafana or Canvas, the payload does not appear to be API compliant. What options are there to possibly suppress or deactivate the displayed error message?
