Hey there,
I'm going around in circles trying to configure my neo4j / rails backend to accept http requests from a client to create a user, using rails routes and controllers. I'm testing using Postman against localhost, but have also tried and failed to use curl. No matter what data I send to the request, I receive an empty 404 response that is not logged by rails, but is logged by neo4j in the http logs.
I strongly suspect that I have either totally misunderstood how rails and neo4j should be working together, or I have misconfigured my http setup. Any clues would be much appreciated. I'll try to put the relevant code below, and many thanks in advance.
Attempted request log:
