This is the complete error message I receive. It doesn't have anything to do with the code I wrote. Maybe there is something wrong with the dependencies but I couldn't figure out what. What may be the cause behind this?

Answer 1

You're mixing incompatible spring and spring boot versions. Please check comparability in maven dependency.
