Unable to create a message with map<string, map<string, list<double>>>

[GiulioRomualdi]

Describe the bug I tried to create a message with map<string, list<map<string, list<double>>>> entry, but the code fails in creating the thrift. To Reproduce Steps to reproduce the behavior: I created a commit that can be used to check the problem: https://github.com/GiulioRomualdi/yarp/commit/0a59ebcd7d32736dc037ac70ac8a555f9f6eb3a4

To reproduce, compile yarp with tests and run

ctest -R idl::thrift::demo::run --output-on-failure

Expected behavior It should be able to generate the message

Screenshots

This is the error I got
