Corrupt rrd files?

I mainly use cacti for Weathermaps, and I do have lots of them. Since some weeks the Weathermaps don't show data anymore.
The only thing I can find in the logs is the following:
11/03/2022 10:25:18 AM - WEATHERMAP: Poller[0] WARNING: [Map 65] datacenters_new: ReadData: LINK ap0022rp2-MPLS, target: /var/www/html/cacti/rra/adnt-pa0022rp2_traffic_in_52433.rrd on config line 522 of /var/www/html/cacti/plugins/weathermap/configs/datacenters_new had no valid data, according to WeatherMapDataSource_rrd
If I remove and recreate the graphs for this device, and I reassign them to the Weathermap, everything works again.

As said I have many of them so this will be very time consuming - any hints on how to fix this?

I'm not a weathermap person, but I suspect that your devices are re-indexing (changing their index) and your Cacti is not keeping up. What version of Cacti?

Using the most recent 0.8.8a build
In the mean time we're migrating it to a Windows based system and are recreating the Weathermaps from scratch so not that urgent of an issue anymore but if there's an easy fix we could run them in parallel until the new system is up.

Awesome!
