Sensor if giving NaN(0) sometimes

Hi,

I am scraping the sensor data with the API. This has been working for years, i am using a payed subscription. Now for Some reason PVOutput is returning NaN (0) for the energy_consumption often. Not always, but this is giving strange graphs.

Is there something changed in the PVOutput API? On the website the graph and RAW data js showing correctly.

Thanks

Please provide a sample of the API request, removing API key information of course.
