In a Spring Boot application (Spring Boot 2.7.3) using both spring-boot-starter-couchbase and spring-boot-starter-devtools during application startup this exception happens:
com.couchbase.client.core.error.ConfigException: Could not locate a single global configuration
The application runs fine nevertheless and is passing all tests.
However, if I boot the application with devtools disabled (spring.devtools.add-properties=false), the exception does not happen. So it looks like spring devtools and the Couchbase Java SDK interfere with each other.
