Node red stops flows due to missing nodes. When I try to install those node, it fails with a message in the log about unable to locate node-red-contrib-date in the repository
Which contrlb you want to install? I don’t think there’s a node-red-contrib-date, so you likely use another outdated contrib which tries to relay upon auch a non existant thing?
Needs more information … which node is missing, which contrib did provide that earlier?
Perhaps you post a flow for more information.
