Research direction
The issue requires adding support for the HTTP HEAD method in the ZendExpressivePathHandlerServerCodegen class. The error occurs in the postProcessOperations method at line 150 of ZendExpressivePathHandlerServerCodegen.java. You need to add HEAD to the list of allowed HTTP methods, similar to how other methods are handled. Review the swagger codegen source code to understand the pattern for adding new operations.
