Description
eacdy opened DATAMONGO-2146 and commented
I use Spring Boot 2.1.0 with Spring Data Mongo Reactive.
When I call http://localhost:8080/query or http://localhost:8080/query2
I Can only get an error messge like below:
Whitelabel Error PageThis application has no configured error view, so you are seeing this as a fallback.Wed Nov 28 01:35:02 CST 2018There was an unexpected error (type=Internal Server Error, status=500).DBRef resolution is not supported!
When I downgrade to Spring Boot 2.0.6, everything turns OK.
