I solved it by editing the catch.hpp file as shown here:

https://github.com/catchorg/Catch2/blob/d71b4617e9935f8589870af211f5b7552d743654/single_include/catch2/catch.hpp#L10818

To be more precise I replaced the code in

/home/workspace/restbed/dependency/catch/single_include/catch2/catch.hpp

with the code from the file that @mattiadido95 mentioned.
