Hii,
i followed the keycloak documentation and created the themeSelector SPI,
also set it as default themeSelector, by adding entry to the standalone.xml file and added themeSelectorSPI to the deployments directory of keycloak server.
but the server is not able to start and getting below error
and server doesn’t start
I already followed the existing questions solutions
Error Log which prevent keycloak server from starting:
