Adding the following line
debug=true
to the application.properties or application.yml, file should help. You’ll get more detailed logging. Generally, if you want to see more fine-grained log messages from all members of a given package, you can set that by adding a line such as
logging.level.<package_name>=<LOGGING_LEVEL>
for example:
logging.level.org.springframework.context=DEBUG
These log messages may be helpful to find the core of the problem (in this case why a given exception was thrown)
