According to the documentation, I need to update the REST configuration for each entity type. RESTUI seems not to work with 8.2.3, so I figure I'm supposed to update this by hand, for example in rest.resource.entity.node.yml.
I do that, and then I'm stuck. Where does this file go? Does it go in my code somewhere? Am I supposed to import it through Configuration Synchronization (admin/config/development/configuration/single/import)?
I did try to import using Config Synch, but I got the following error, which means nothing to a newbie like me:
An entity with this machine name already exists but the import did not specify a UUID.
Sorry if this is already documented somewhere, but I can't find an explanation anywhere for how to update these settings, and they seem pretty important for using the REST services. I'm currently using the Features Module as a workaround but it's kind of an ugly approach for something that seems like it should be simple.
Thanks in advance!
