Wrong url for dataset on the metadata card
The url is wrong when you try to access the dataset (on staging):
It looks like the whole prefix is missing from the url.
The button points to https://nomad-lab.eu/dataset/id/__RMQje2SLic8CmVWq5czQ
instead of https://nomad-lab.eu/prod/v1/staging/gui/user/datasets/dataset/id/__RMQje2SLic8CmVWq5czQ
