Camunda Upgrade - org.apache.commons.lang error

camundaupgradebug.txt (12.0 KB)
Hi All,
We are upgrading the camunda from 7.10 to 7.15 version. We are using org.apache.commons.lang package in the code. After the upgrade, org.apache.commons.lang was throwing an error- “package org.apache.commons.lang does not exist”

after replacing lang with lang3, build was successful. but we are getting runtime error-“org.springframework.core.convert.ConversionFailedException: Failed to convert from type [byte[]] to type [java.lang.Object] for value”

Please help
