Additional Versions
Product
Component	Studio
Problem Description	Assume a route that uses a context variable called My_Var (set to some value). It runs successfully from Studio. But if this route is built as an ESB Microservice (Spring Boot), then the execution fails because the value of the context variable My_Var is null.
Problem root cause	There is a limitation from Spring Boot that a combination of underscores and upper-case in context variable names does not work as a property name.
Solution or Workaround	Rename the context variable name by removing the underscore (MyVar for example) or use only lower-case with underscores (my_var for example).
