WCS vignette with error.

[Emanuele Cordano]

I rerun automatically all the chunks of the WCS vignette and the following error occurs (SEE BELOW) , when the SpatRast object should have been returned. Is it an issue of the WCS URL used?
Thank you
Best

Thanks i will check. They mave have changed something in the Rasdaman test service I used for the Vignette.

[Emmanuel Blondel]

Something goes wrong in Rasdaman test server that is used in the examples. I've contacted their team.

[Emanuele Cordano]

Thank you and compliments for your package.
