Micronaut openapi issue with additionalPropertiesSchema

[amaresh309]

I am using micronaut 4.7.4 along with openapi libraries to generate openapi schema from java object. However when I am trying to use additionalPropertiesSchema I am getting error. Any clue?

dependencies from gradle.

id("io.micronaut.application") version "4.4.4"
id("io.micronaut.aot") version "4.4.4"
